ZHANG Xi-tian, HAN Xiao-zu. STUDIES ON THE 13C-NMR SPECTRA OF ALTERNATING COPOLYMERS OF CONJUGATED DIENES WITH METHYL ACRYLATE[J]. Acta Polymerica Sinica, 1985,(4):293-298.DOI:
spectra of alternating copolymers of conjugated dienes
e.g. butadi-ene(BD)
isoprene(IP) and chloroprene(CP)
with methyl acrylate(MA) were studied. It was proved that they are all alternating copolymers. The BD units in poly(BD-a-Ma) are mainly in the form of trans-1
4-structure. The contents of trans-1
4-
cis-1
4- and 1
2-structure are 88
7 and 5%
respectively. The IP and OP units in poly(IP-a-MA) and poly(CP-a-MA) are present essentially in trans-1
4-configuration and link with MA units predominantly in the "head to head"arrangement while CP-CP units pre-sent in the latter with a small quantity.
