“…Therefore, the objective of the modification of HBR with acrylic monomers is to obtain a synergetic compromise between most needed properties. The study of alkyd-acrylic resins or oil-acrylic monomers has been only focused on materials synthesis with the lowest branching degree [17][18][19][20][21][22] . There are two methods usually employed to synthesize alkyd-acrylic resins, which are emulsion polymerization [22] , and mini-emulsion polymerization [13,14] .…”

There are two methods usually employed to synthesize alkyd-acrylic resins, which are emulsion polymerization [22] , and mini-emulsion polymerization [13,14] . The emulsion polymerization is not a suited method, because alkyd resins exhibit low hydrophilicity, since the diffusion of alkyd resins toward micelles is very slow, which produces colloidal instability (phase separation or secondary nucleation) [7,15] .…”

SbstractFour waterborne hyperbranched alkyd-acrylic resins (HBRAA) were synthesized by miniemulsion polymerization from a hyperbranched alkyd resin (HBR), methyl methacrylate (MMA), butyl acrylate (BA) and acrylic acid (AA), by using benzoyl peroxide (BPO) and ammonium persulfate (AP) as initiators. The reaction between HBR and acrylic monomers was evidenced by differential scanning calorimetric (DSC), nuclear magnetic resonance (NMR) and gel permeation chromatography (GPC). The conversion percentage, glass transition temperature (T g ), content of acrylic polymer (determined by soxhlet extraction) and molecular weight increased with the content of acrylic monomers used in the synthesis. The main structure formed during the synthesis was the HBRAA. The analysis by dynamic light scattering (DLS) showed that the particle size distribution of HBRAA2, HBRAA3 and HBRAA4 resins were mainly monomodal. The film properties (gloss, flexibility, adhesion and drying time) of the HBRAA were good.

“…Many studies have started focusing on the development of polymeric materials based on plant seeds and oils [1][2][3][4] because of the rising cost of petroleum products and environmental concerns. Vegetable oils have been an important source for the synthesis of ''green'' polyesters or alkyd resins.…”

Effect of methyl methacrylate content on coatings’ properties of palm oleic acid-based macromer

The macromer was synthesized using medium oil length oleic acid, phthalic anhydride, and glycerol. The synthesized macromer and methyl methacrylate (MMA) were copolymerized by free radical polymerization in toluene. The ratio between the macromer and MMA changed, and the effects on different properties of the copolymers, such as glass transition temperature (T g ) and film properties, were studied. The macromer and copolymer structures were characterized by FTIR and 1 H NMR spectroscopies. The coatings prepared with the highest ratio of MMA exhibited better overall physico-chemical properties. Alternatively, Tafel polarization curves showed that the corrosion rate value in NaCl solution decreases significantly when the MMA content is increased. Dynamic mechanical analysis results revealed that the increasing amounts of MMA lead to increasing T g values of copolymers.

“…Alkyd resins, being in this category, are important area in the industry, as one can just design alkyds by changing the oil length and subjected them to suitable physical or chemical modifications for various potential applications such as surface coating, adhesive, printing ink, fibers and temperature resistant performance materials pneumatic tire and so on [1][2][3][4][5][6][7]. However, some health problems may arise from thermal decomposition of the materials due to evolution of some toxic products.…”

Study of Thermal Decomposition Kinetics of Palm Oleic Acid-Based Alkyds and Effect of Oil Length on Thermal Stability

et al. 2011

View full text Add to dashboard Cite

Thermal decomposition kinetics of three palm oleic acid-based alkyds with different oil lengths and having different molecular weights were studied using TGA measurements under non-isothermal conditions. Activation energies were obtained from Kissinger and Ozawa, Flynn and Wall (OFW) methods and subsequently the pre-exponential factor, A, degradation rate constant, k, for all the alkyds were also determined. From kinetic analysis of the thermal decomposition using the OFW method, it was found that degradation of all the alkyds has taken place in more than two stages, corresponding to different mechanisms. As shown from Ozawa and Kissinger methods, the chemical composition of the alkyds influenced the thermal degradation; increasing the phthalic anhydride and glycerol, and decreasing the oleic acid increased the thermal stabilities of the alkyds.
