Polyacrylate latexes present good film-forming property, and therefore are used in a wide range of applications including coatings, adhesives, additives for paper, textiles, wood, and leather. However, some drawbacks, such as poor elasticity and low hardness have restricted their applications. This review summarizes recent development of polyacrylate latexes modified by polyurethane, organic fluorine, and inorganic nanoparticles, separately, which most often exhibit superior properties to those of their individual components. For each modification method, a comment is given based on our knowledge and related research experience. At last, some perspectives on the future research and development of modification of polyacrylate latexes are concluded.

“…Bulk polymerized methacrylates are widely used as materials in dentistry [34], but when polymerized in solution, they can be used as varnishes [35], and suspension polymerization results in acrylic beads [36]. Emulsion polymerization has been an important and widely used process for the manufacture of polymer products, e.g., paints, adhesives, coatings, and binders [37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54]. One of the advantages of this process is the possibility of obtaining polymers of high molecular weight at a reasonable rate of reaction.…”

Acrylic copolymers have achieved prime importance in various avenues of industrial application such as adhesive in packaging and construction, binder and stabilizer in textiles, base coat in leather, topcoat in fl oor polish, pigment binder in paper industries, etc. Acrylic resins are generally known to have superior exterior durability and weather resistance compared to other organic binders/fi lm-formers commonly used in surface coatings. Th e emulsion polymerization of acrylic monomers provides a good combination of performance properties required in fi lm formation. Th ese properties depend on the copolymer composition, particle size, molecular weight, glass transition temperature (Tg), morphology of the latex particles, etc.In this chapter, the reaction components and polymerization process conditions that aff ect the inherent characteristics of the polymers are presented. Th ere is a discussion of the incorporation of comonomer, which would lead to an improvement in the fl exibility of fi lms produced along with adhesion, gloss, hardness, solvent resistance, water resistance, etc. Also, there is a recently developed successful approach for achieving balanced properties which involves the copolymerization of fi lm-forming monomers like acrylate and methacrylates with crosslinkable monomers.

“…Some studies have reported the synthesis and properties of selfcross-linkable fluorinated acrylate copolymer emulsions [21,28,29], but there has been little research on the optimum content of hydrophobic bulky alkoxysilanes for improving the water/oil repellency (low surface tension) and mechanical properties. In an earlier investigation of the synthesis and surface properties of self-crosslinking core-shell acrylic copolymer emulsions containing fluorine/silicone in the shell, we found that the optimum vinyltriethoxysilane (VTES) content was about 6 wt% to obtain a high water/oil repellent coating material [30].…”

A series of UV-curable polyurethane acrylates containing fluorinated acrylic monomer (heptadecafluorodecyl methacrylate, PFA, 6 wt%)/ vinyltrimethoxysilane (VTMS, 0-9 wt%) [FPUA6/0, FPUA6/3, FPUA6/6 and FPUA6/9, where the numbers indicate the wt% of PFA/VTMS] were synthesized from a reactive urethane oligomer (40 wt%) and diluents (60 wt%). This study examined the effect of bulky VTMS (0-9 wt%)/bulky IBOA (34-25 wt%) weight ratio on the properties of the UV-curable polyurethane acrylates for transparent anti-fouling coating materials. In the wavelength range of 400-800 nm, the transmittance % of the FPUA film samples increased markedly up to nearly 100 % with increase in the VTMS content up to 9 wt%. As the VTMS content increased, the storage modulus/ tensile modulus/hardness of the UV-cured film samples increased significantly and the tensile strength/glass transition temperature increased a little; however, the elongation at break decreased significantly. XPS showed that the film-air surface of the UV-cured polyurethane acrylate film had a higher fluorine content than the filmdish interface indicating the gradient concentration of fluorine in the structure of the film from the film-air surface to the film-glass interface. As the VTMS content increased from 0 to 9 wt%, the surface tension of the UV-cured urethane acrylate films decreased from 17.2 to 15.9 mN/m, whereas the water/methylene iodide contact angles of the film-air surface increased significantly from 107.9/80.9°to 114.2.9/ 84.2°. These results suggest that the UV-curable polyurethane acrylate containing 9 & Han Do Kim
