Effect of polymer composition on performance properties of maleate-vinyl ether donor-acceptor UV-curable systems

Novel in situ synthesis in the preparation of ultraviolet‐curable nanocomposite barrier coatings

“…In previous studies, we reported the development of UV‐curable coatings and polymer/clay nanocomposites based on the nonacrylate technology of donor‐acceptor chemistry 37, 38. Sonication was used to disperse the clay and monomers before photocopolymerization, and the resulting nanocomposite morphology was classified as intercalated.…”

“…The benefits of using donor‐acceptor chemistry include high flexibility in polymer backbone design, low toxicity of monomers, and comparable cure times to acrylate systems. UV‐curable coatings and polymer/clay nanocomposite systems based on maleate‐vinyl ether donor‐acceptor chemistry has previously been reported 37, 38. Maleic anhydride was used as a monomer in the synthesis of unsaturated polyester resins.…”

Properties of nanocomposites based on maleate‐vinyl ether donor—acceptor UV‐curable systems

“…Polyester compositions are indicated in Table I and were selected based on the findings in our earlier study. 25 These polyesters were used to prepare nanocomposites and the methodology used is as follows. Coatings were prepared by mixing the unsaturated polyester and triethyleneglycol divinyl ether in a ratio of 1 : 1 of reactive functional groups: maleate to vinyl ether functionality.…”

“…21,22 It has been found that polymerization kinetics are affected by factors such as photoinitiator concentration, presence of oxygen, light intensity, and composition of the monomer mixture. [23][24][25] In this study, UV-curable nanocomposites, based on donor-acceptor chemistry, were prepared. The purpose of the study was to understand the effect of the polymer backbone structure and the type and amount of clay on the thermal, mechanical, and morphological properties and cure characteristics of nanocomposites.…”

Syntheses of novel photosensitive polysiloxanes and their effects on properties of UV-cured epoxy methacrylate coatings

“…[2][3][4][5] Acrylate and methacrylate groups have been employed widely for UV photopolymerization because of their strong reactivity, showing rapid, near-complete conversions (i.e., no residual unreacted monomers) with low heat generation. 6 Customarily, the main types of monomers/ prepolymers used in UV-curable systems are epoxy acrylate, 7,8 urethane acrylate, 9 unsaturated polyesters, 10,11 and polyether acrylate. 12 Bisphenol-A epoxy methacrylate/acrylate resins are definitely one of the most important classes of UV-curing polymers.…”
