A polymerization process for obtaining polymers of low molecular weight

摘要

There is provided a process for the preparation of a polymer which process comprises carrying out, in solution, polymerization of the desired monomer or monomers in the presence of a complex of an electron donor and an electron acceptor which complex is capable of dissociating to release a free radical and a cation and of a free radical quencher. The polymerization process of the present invention is a charge transfer polymerization in the presence of a free radical quencher. This process may be used to prepare polymers of low molecular weight at high yield.
