Acrylic polymer latex has versatile role in many academic and industrial applications like paint, adhesives, textile, paper industry, concrete, surface coating, synthetic rubber and many ones. Acrylic base polymer latex can be prepared by various polymerization methods like Batch emulsion, Seeded emulsion, Situ miniemulsion, Atom transfer radical, Free radical copolymerization, Pickering miniemulsion, Semi-continuous seeded emulsion, dispersion copolymerization, aqueous suspension polymerization etc. in different solvents i.e. 1,1,2-trichloroethane, water, deionized water, 1,4-dioxane, chloroform, tetra hydro furan, toluene, benzene, nitric acid and so on. Acrylic latexes possessed various properties such as increased particle size which resist centrifugal nature and reduce viscosity of heavy oil, layered coating on steel improve lustre along with flexibility, tensile strength and thermal stability too. Acrylic latexes increase silicon intensity in silicon nanoparticles by controlling pH of emulsion during polymerization and also super paramagnetic behaviour of Fe2O3 nanocomposites latex controlled by pH. In this connection, many researchers have synthesized various acrylic base polymer latex or its composites, investigate its utility in different forms for different purposes to improve properties as required. In this review our main emphasis is to investigate the synthesis, characterisation and application of various acrylate polymer latexes.

“…At present, there are few studies on self-crosslinked long fluorocarbon acrylate polymer emulsions, and most of them are independent studies on self-crosslinked acrylate polymer emulsions and fluorocarbon acrylate polymer emulsions (Kim et al, 2017;Chen et al, 2018;Chen et al, 2008;Dou et al, 2014;Lu et al, 2019;Lian, 2018;Wang, 2009;Mondal et al, 2021;Machotova et al, 2020). The application of cross-linking monomers in the preparation of polymer emulsions mainly uses the cross-linking monomers themselves or with other monomers to form cross-links to transform polymer molecules from a linear structure to a network structure, which can significantly improve the properties of the polymer, hydrophobicity and friction resistance of the product (Meng et al, 2020).…”

Purpose Self-crosslinked long fluorocarbon acrylate polymer latex has good hydrophobic and oleophobicity, weather resistance, aging resistance, stability and other excellent properties, which make the polymer be widely used in coatings, dyes, adhesives and other products. The purpose of this study is to prepare self-crosslinked long fluorocarbon acrylate polymer latex via semi-continuous seeded emulsion technology and carry out comparative study on two different cross-linked monomers. Design/methodology/approach Methyl methacrylate (MMA) and butyl acrylate (BA) were used as the main monomers, dodecafluoroheptyl methacrylate (DFMA) as the fluoromonomer, hydroxypropyl methacrylate (HPMA) and N-methylol acrylamide (NMA) as cross-linked monomers, and 1-allyloxy-3–(4-nonylphenol)-2-propanol polyoxyethylene (10) ether (ANPEO10) and 1-allyloxy-3–(4-nonylphenol)-2-propanol polyoxyethylene (10) ether ammonium sulfate (DNS-86) as compound emulsifiers via the semicontinuous-seeded emulsion polymerization. Findings The properties of the polymer emulsions, which are prepared with two different cross-linked monomers, are compared and discussed, and it is concluded that HPMA is more suitable for the preparation of self-crosslinked polymer emulsions. The formula of the polymer latex is ANPEO10: DNS-86 = 1:1, and the mass ratio of the monomers used in the polymer is MMA: BA: DFMA: HPMA = 14.40:14.40:0.60:0.60. Practical implications Self-crosslinked long fluorocarbon acrylate polymer latex can be used in many fields such as coatings, dyes, adhesives and other products. Originality/value The self-crosslinked long fluorocarbon acrylate polymer latex is prepared by mixing the nonionic emulsifier ANPEO10 and the anionic emulsifier DNS-86 when potassium persulfate is used as the thermal decomposition initiator and the semicontinuous-seeded emulsion technology is adopted and the comparative study on two different cross-linked monomer is carried out, which is not reported in the open literatures.

“…At present, there are few studies on self-crosslinking fluorocarbon acrylate polymer, mostly for self-crosslinking modification or fluorine modification (Kim et al , 2017; Chen et al , 2018; Chen et al , 2008; Lu et al , 2019; Mondal et al , 2020). The use of fluorinated monomers and cross-linking monomers alone resulted in poor performance or failed to achieve desired results.…”

Purpose Fluorine materials have received the keen attention of many researchers because of their water repellency and low surface free energy. The purpose of this paper is to prepare self-crosslinking fluorocarbon polyacrylate latexes containing different fluorocarbon chain lengths by semi-continuous seeded emulsion polymerization technology. Design/methodology/approach Methyl methacrylate (MMA), butyl acrylate (BA), hydroxypropyl methacrylate (HPMA) and fluorine-containing monomers were used as main monomers. The fluorine-containing monomers included hexafluorobutyl methacrylate (HFMA), dodecafluoroheptyl methacrylate (DFMA) and trifluorooctyl methacrylate (TFMA). Potassium persulfate (KPS) was used as thermal decomposition initiator, non-ionic surfactant alkyl alcohol polyoxyethylene (25) ether (DNS-2500) and anionic surfactant sodium dodecylbenzene sulfonate (SDBS) as mixed emulsifier. Findings Through optimizing the reaction conditions, the uniform and stable latex is gained. The polymer of structure was characterized by Fourier transform infrared spectroscopy (FTIR). Thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and contact angle (CA) were tested on latex films. The particle size and distribution range of emulsion were tested with nano particle size analyzer. After comprehensively comparing the latexes and films prepared by HFMA, DFMA and TFMA, the performance of DFMA monomer modified is better. Originality/value The self-crosslinking acrylic emulsion is prepared via semi-continuous seeded emulsion polymerization, which methyl methacrylate (MMA), butyl acrylate (BA), hydroxypropyl methacrylate (HPMA) and fluorine-containing monomers were used as main monomers. The fluorine-containing monomers were composed of hexafluorobutyl methacrylate (HFMA), dodecafluoroheptyl methacrylate (DFMA) and trifluorooctyl methacrylate (TFMA). Potassium persulfate (KPS) was used as thermal decomposition initiator, non-ionic surfactant alkyl alcohol polyoxyethylene (25) ether (DNS-2500) and anionic surfactant sodium dodecylbenzene sulfonate (SDBS) as mixed emulsifier. There are two main innovations. One is that the self-crosslinking acrylic emulsion is prepared successfully. The other is that the effects of monomers containing different fluorocarbon chain lengths on polyacrylate, such as monomer conversion rate, coagulation rate, mechanical stability, chemical stability, emulsion particle size and storage stability, are studied in detail.
