Abstract
Ethyl, isopropyl, β,β,β-trifluoroethyl, and phenyl 1-bicyclobutanecarboxylate monomers were synthesized from 1,1-cyclobutanedicarhoxylic acid.. These bicyclobutanecarboxylates were subjected to free radical polymerization under various conditions. The bicyclobutane monomers behave very similarly to their vinyl counterparts. Chain transfer to polymer occurs to some extent. Excessively high molecular weights and gelation can be controlled by addition of a chain-transfer agent. Poly(methyl 1-bicyclobutanecarboxylate) is an optically clear material with a refractive index of n D 25 = 1.52 and an excellent thermal stability
