Abstract
A styrene resin composition which is admixed with a styrene-vinyl acetate block copolymer is improved in the fluidity without degrading the mechanical strength and electric insulation resistance. Said vinyl acetate block polymer can easily be obtained by using a polymeric peroxide having ester bonds in the molecule thereof, notwithstanding that a copolymer of a styrene and a vinyl acetate could not be prepared easily by the prior art.
