Ih. Donnelly et al., FACILE SYNTHESIS OF VINYL COPOLYMERS WITH OPTICAL-ACTIVITY ARISING FROM THE CONFIGURATION OF STEREOGENIC CARBON-ATOMS IN THE MAIN-CHAIN, Journal of the Chemical Society, Chemical Communications, (12), 1995, pp. 1235-1236
Hydrolytic cleavage of the alkyl chiral auxiliaries from copolymers of
diborneyl and dimenthyl fumarates each with styrene, yields optically
active vinyl copolymers of fumaric acid and styrene in which the chir
ality is due to the main chain.
