Abstract
PURPOSE: To suspension polymerization of a mixture of 2 kinds of specific olefin polymers and a vinyl or vinylidene monomer is conducted in an aqueous medium to produce a polymer blend with high impact strength.
CONSTITUTION: The suspension polymerization is effected on a mixture consisting of (A) 100 parts by wt of a particulated olefin polymer with an average particle size of 0.3 W 5 mm resulting from mixing (a) 99 W60 wt% of a proplyene polymer of over 75 wt% propylene content or high-density polyethylene with a density of 0.935 W 0.975 g/cm3, and MI of 0.01 W 100 g/min under 2.16 kg load with (b) 1 W 40 wt% of a block copolymer of formula I, II, and III (A is polystyrene having a glass transition point higher than room temperature; B is a polyconjugated diene having a glass transition point lower than room temperature; n≥2; the molecular weight of B is larger than that of A in at least one pair of A and B and the molecular weight of A is 2000 W 100000 and that of B is 5000 W1000000) and (B) 5 W 200 parts by wt of a vinyl or vinylidene monomer as vinyl or vinylidene chloride.
