説明

1-Hexene-3, 4-dicarboxylic anhydride (1a), (E) -2-hexene-3, 4-dicarboxylic anhydride (2a), dimethyl 1-hexene-3, 4-dicarboxylate (1e) and dimethyl (E) -2-hexene-3, 4-dicarboxylate (2e) do not radically homopolymerize. Radical copolymerization of these monomers (M2) with acrylonitrile (AN, M1) was conducted at 60°C with AIBN, and the following monomer reactivity ratios were obtained:<BR>AN-1a r1=5.02, r2=0.00<BR>AN-2a r1=15.98, r2=0.00<BR>AN-1e r1=8.46, r2=0.00<BR>AN-2e r1=17.40, r2=0.00<BR>At the same M1/M2 feed ratio, the terminal-olefinic monomers (1a and 1e), whether acid anhydride or ester, led to higher contents in the copolymers than the inner-olefinic counterparts (2a and 2e, respectively). The viscometric molecular weights of the copolymers decreased significantly with a decrease in acrylonitrile content in the monomer feed. For the AN-2a and AN-2e copolymers, the two types of methyl groups, one attached to the main chain and the other to the side chain, were discriminated by 1H NMR spectroscopy. 1H NMR analysis of the AN-1a and AN-1e copolymers thus showed that they did not contain repeat units derived from 2a and 2e which would be formed by migration of the double bond of 1a and 1e, respectively.
