HCID 168239Isoprene acrylonitrile

Conditions

Temperature
80 °C

Procedure

Then, was added thereto 68.2 parts of isoprene and 1.79 parts of 2-chloropropionitrile as an organic halide, followed by stirring at 80° C. to conduct a polymerization reaction. After 114 hours, the same post-treatment as in Example 1 was carried out to give a random (isoprene/acrylonitrile) copolymer. The conversion rate of isoprene was 62% and the conversion rate of acrylonitrile was 64%. The analysis results of the random (isoprene/acrylonitrile) polymer obtained are shown in Table 5. The polymer was confirmed to have a chlorine atom at the terminal of the polymer chain.
