摘要

The 13C-NMR spectra of alternating copolymers of conjugated dienes

butadiene (BD)

isoprene(IP) and chloroprene (CP)

with methyl acrylate (MA) were studied. It is proved that they are allalternating copolymers. The BD units in Poly (BD-alt-MA) are joined to MA mainly in the form of trans 1

4-structure. The contents of trans 1

cis 1

4-and 1

2-structure are 88

7 and 5%

res-pectively. The IP and CP units in Poly(IP-alt-MA) and Poly(CP-alt-MA) exist essentially as trans1

4-configuration and connect with MA units in "head to head"arrangement predominantly

while CP-CP units present in Poly(CP-alt-MA) in a small quantity.
