Copolymers were synthesized from tung oil and 1,6 hexanediol diacrylate or 1,4-butanediol diacrylate via the Diels-Alder reaction. The copolymers were completely soluble in common laboratory solvents, and had very broad molecular weight distributions. The residual double bonds in the copolymers were used to cure films by oxidative means. The films had good solvent resistance, good gloss, and a reasonable hardness-flexibility balance.

The title monomer was synthesized from 3‐isopropenyl‐α,α‐dimethylbenzyl isocyanate in a significantly better yield than was previously reported. 3‐Isopropenyl‐α,α‐dimethylbenzylamine proved incapable of homopolymerization using free‐radical initiation but readily copolymerized with a variety of commonly available monomers under free‐radical conditions. Films of some of the copolymers were prepared and crosslinked using a variety of multifunctional epoxy compounds. The films had good solvent resistance, high hardness, and good gloss. © 2001 John Wiley & Sons, Inc. J Appl Polym Sci 82: 1030–1039;2001
