Copolymer sequence control by ring-opening polymerization of prestructured cyclic monomers

In search for the new synthetic methods which may lead to the copolymers of controlled mer sequences, several new carbocyclic and heterocyclic monomer systems such as 1,1-disubstituted 2-vinylcyclopropanes, 1-(p-anisyl)-2-vinylcyclopropanes, substituted 3,4-dihydro-2H-pyrans, substituted 4-vinyl-2-oxetanones and α-vinyl cyclic sulfones were synthesized and their polymerization behaviors were investigated. And other promising monomer systems were also examined.
