Notes:
Dimethyl 4-methyl-1-pentene-2,4-dicarboxylate (3) and trimethyl 4-methyl-1-octene-2,4,7-tricarboxylate (4) are not radically homopolymerizable. Dimethyl 1-hexene-2,4-dicarboxylate (5) polymerizes slowly to yield a small amount of oligomers. Homopolymerization of dimethyl 1-butene-2,4-dicarboxylate (6) affords a high-molecular-weight polymer. Radical copolymerization of these methyl α-substituted acrylates (M2) with styrene (M1) was carried out at 60°C using AIBN, and the following monomer reactivity ratios were obtained; 3: r1 = 0,983, r2 = 0,000; 4: r1 = 0,938, r2 = 0,000; 5: r1 = 0,672, r2 = 0,119; 6: r1 = 0,566, r2 = 0,195. The polymerizability of these methyl acrylate derivatives is influenced by the steric effect of the α-substituents.
