Styrene → Prop-2-enenitrile--ethenylbenzene (1/1)

Participants

Reaction Steps

A graft precursor was prepared by following the procedure of Example 13, except that a mixed monomer consisting of 210 g of styrene, 90 g of acrylonitrile, and 0.6 g of n-dodecyl mercaptan as a molecular weight regulator was used in the place of 300 g of styrene. Separately, an acrylonitrile-styrene copolymer was obtained by placing a mixed solution consisting of 70 g of styrene, 30 g of acrylonitrile, 0.2 g of n-dodecyl mercaptan, and 0.5 g benzoyl peroxide in 500 g of an aqueous 1% polyvinyl alcohol solution and holding the resultant mixture at a temperature of 80° to 85° C. for seven hours to complete polymerization. Graft resin compositions were produced by following the procedure of Example 13, except that the amounts of the copolymer, the graft precursor mentioned above, the propylene polymer to be mixed were varied as indicated in Table 7. The results were as shown in Table 7.
