Abstract: The cyclized random copolymers of cis-i, 4-butadiene and isoprene have been investigated by using pyrolysis-gas chromatography. The results show that the amount of main pyrolysis products changes regularly with the degree of cyclization. Both units of butadiene and isoprene participate in cyclization, but the butadiene units are less liable to be cyclized.

Key words: cis-1,4-polybutadiene, polyisoprene, pyrolysis-gas chromatography, cyclization
