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

Participants

Reaction Steps

Graft polymerization precursors were manufactured in the same manner as in Examples 84 to 87 except that a monomer mixture consisting of 210 g of styrene and 90 g of acrylonitrile was used in lieu of 300 g of styrene, and 0.6 g of n-dececyl mercaptan was used as a molecular weight adjusting agent. Separately, acrylonitrile-styrene copolymer was prepared by adding 70 g of styrene, 30 g of acrylonitrile, 0.2 g of n-dodecyl mercaptan and 0.5 g of benzoyl peroxide to 500 g of a water solution containing 1% polyvinyl alcohol and holding the resultant admixture at a temperature of 80° to 85° C. for 7 hours to complete the polymerization. Graft resin compositions were manufactured in the same manner as in Examples 84 to 87 except that the amounts of this copolymer and the graft polymerization precursor and ethylene copolymer noted above as in Tables 35 to 38. The results are as shown in Tables 35 to 38.
