G. Wulff et al., TEMPLATE-INDUCED CONTROL OF STEREOCHEMISTRY FOR THE SYNTHESIS OF LINEAR VINYL-POLYMERS, Macromolecular symposia, 101, 1996, pp. 355-362
Asymmetric cyclocopolymerization of judiciously designed bifunctional
monomers with a number of common comonomers affords optically active v
inyl polymers with main chain chirality. Tacticity and sequence of com
onomeric units can be controlled and thus complicated structures built
up. Under different reaction conditions the same bifunctional monomer
1 can undergo cyclization involving a 19-, a 21-, or an 18-membered r
ing. With monomer 3 an 11-membered ring is formed.
