Vorschrift

A random (isoprene/acrylonitrile) copolymer was prepared in the same manner as in Example 10, except that the amount of toluene was changed to 262 parts, that 3.70 parts of methyl α-chlorophenyl acetate was used as an organic halide in place of 1.79 parts of 2-chloropropionitrile, that 8.25 parts of 2,2′-azobis(isobutyronitrile) (hereinafter, sometimes referred to as “AIBN”) was further added as a radical generator, and that the reaction time was changed to 72 hours. The conversion rate of isoprene was 78% and the conversion rate of acrylonitrile was 68%. The analysis results of the random (isoprene/acrylonitrile) copolymer obtained are shown in Table 7. The polymer was confirmed to have a chlorine atom at one terminal of the polymer chain.
