Abstract

PURPOSE: To obtain a resin having a good balance between impact resistance and fluidity, by adding first a monofunctional organic peroxide and then a bifunctional organic peroxide, in polymerizing a styrene type monomer containing a dissolved high-cis content polybutadiene.
CONSTITUTION: In polymerizing 98W80pts.wt. styrene monomer containing 2W 20pts.wt. dissolved high-cis content polybutadiene, cis-1,4 addition ≥90mol%; the polymerization is carried out in such a manner that a monofunctional organic peroxide of formula I, wherein R1 and R2 are each methyl, ethyl or phenyl, is added during the period till the conversion of the styrene type monomer reaches 25% and, then, at least one bifunctional organic peroxide of formula II, wherein R3 and R4 are each an alkyl, or of formula III, wherein R2 is defined as above, R5 is an alkylene and R6 is an alkoxycarbonyl, is added during the period in which the conversion of the styrene type monomer is 5W40%. This makes it possible to produce titled resin having excellent heat resistance, an excellent balance between impact resistance and fluidity, and excellent tapping strength.
