Synthesis and photopolymerization of acrylic acrylate copolymers

Abstract

Acrylate-functionalized copolymers were synthesized by the modification of poly(butyl acrylate-coglycidyl methacrylate) (BA/GMA) and poly(butyl acrylateco-methyl methacrylate-co-glycidyl methacrylate).13 C-NMR analyses showed that no glycidyl methacrylate block longer than three monomer units was formed in the BA/ GMA copolymer if the glycidyl methacrylate concentration was kept below 20 mol %. We chemically modified the copolymers by reacting the epoxy group with acrylic acid to yield polymers with various glass-transition temperatures and functionalities. We studied the crosslinking reactions of these copolymers by differential scanning calorimetry to point out the effect of chain functionality on double-bond reactivity. Films formed from acrylic acrylate copolymer precursors were finally cured under ultraviolet radiation. Network heterogeneities such as pendant chains and highly crosslinked microgel-like regions greatly influenced the network structure and, therefore, its viscoelastic properties.

(Meth)acrylic Cross-Linked Polymer Microparticles: Synthesis by Dispersion Polymerization and Particle Characterization

“…They can be useful as solid lubricant, as support for catalysts, [10,17] or as cross-linking agent to improve the film formation [18 -21] and the film mechanical properties. [22] There are various ways to prepare cross-linked microparticles. They can be obtained when cross-linking is carried out in very high dilution.…”

Development and assessment of the advanced graft copolymers obtained from Hibiscus sabdariffa biomass

“…17 The potential applications of graft copolymerization could be immensely increased by selecting various initiators like ceric ammonium nitrate (CAN), potassium per sulphate (KPS), and ammonium per sulphate (APS). 18 Researchers have used different vinyl monomers with varied backbones such as poly(butyl acrylate), 19 poly(methyl acrylate), 20 poly(acrylic acid), poly(vilidene fluoride), 21 glycol polymers, 22 and cellulose 23 to get increased graft yield, hydrophobicity, chemical resistance, and physical strength.…”

Synthesis of Gemini‐Like Methyl Acrylate‐Acrylic Acid‐Methyl Acrylate Triblock Copolymers Surfactants by RAFT Polymerization in Solution and Investigation of their Behavior at the Air–Water Interface

“…Although block copolymers of acrylate-acrylic acid have been extensively studied [16][17][18][19][20][21][22][23], the effect of molar ratio [n(MA)/n(AA)] and RAFT agent percentage on Mn and polydispersity index (PDI) have long been neglected. General focus was on the relationship between reaction time and molecular weight in polymerization methods like emulsion polymerization [2].…”
