Molecular design and application of divinyl monomers to synthesis of UV-curable latex

A new method for simplifying the preparation of unsaturated latex was investigated. Four divinyl monomers were designed, and based on quantum chemical calculations, (z)-4-(2-(acryloyloxy)ethoxy)-4-oxobut-2-enoic acid (cis-AEOEA) was selected as the only nonelectron-donating divinyl monomer whose active double bond is prone to polymerize, while the inactive one is left in polymer form. The inactive double bond can also be activated by the formation of charge transfer complex polymerization systems with electron-donating comonomers and activity that is in direct proportion to the electron-donating ability of comonomers. This result was proved using an orthogonal experimental design L9₃⁴, and the UV-curing performance of unsaturated latex membranes was studied.
