Acrylate and Methacrylate Containing Terpolymers

In addition to the terpolymers previously mentioned that contain acrylates,the methyl acrylate-MA and methyl methacrylate-MA monomer pairs have been copolymerized with each other, acrylic acid, 2-ethylhexyl acrylate, ethyl acrylate, glycidyl methacrylate, acrylonitrile, vinylidene chloride, and isobutyl vinyl ether. 

Compositional determinations for the methyl methacrylate-MA-methyl acrylate terpolymers, prepared with BPO in 2-butanone solvent at 60°C, showed the reactivity of the methacrylate monomer toward the anhydride macroradical is approximately four times greater than that of the acrylate. Even though evidence for charge-transfer complexes between the anhydride-acrylate and anhydride-methacrylate pairs exist (see Chapter 10), there is no evidence that the kinetics of the polymerization is affected by these complexes. 

The copolymerization of isobutyl vinyl ether-MA-methyl methacrylate monomer mixtures were run in sealed tubes at 60°C, with AIBN initiator and 

Terpolymers, prepared from various methacrylate-MA pairs, copolymerization with glycidyl methacrylate and acrylonitrile have been examined in water-soluble films and coatings and wood-plastic combinations. 

The thermosetting coatings exhibited excellent protective and decorative properties. Wood-plastic combinations prepared by this procedure exhibited excellent dimensional stability and other properties, due to significant condensation reaction of the anhydride groups with cellulosic hydroxyl residues.
