ABSTRACT:
A novel high-impact polystyrene composition superior to conventional high-impact polystyrene composition, in low temperature high-impact properties, tensile strength, processability, toughness, stiffness, etc. can be obtained by a radical polymerization of a mixture of (1) 2-20% by weight of a random copolymer having a composition of continuously and gradually reduced styrene content along the polymer chain of the copolymer which is obtained by the solution polymerization of butadiene and styrene in the presence of a lithium base catalyst and (2) 80-98% by weight of styrene, carried out in bulk polymerization manner or in a manner in which bulk and suspension polymerizations are used in series.
