Abstract
A method of producing a five-carbon ring derivative-containing polyurethane involves introducing a DCPD-derived 5-carbon cyclic compound into a polyurethane material and effectuating polymerization in the presence of a solvent of a low boiling point and low toxicity to produce a five-carbon ring derivative-containing polyurethane of a high molecular weight.
