<p>Blended compsn. comprises (A) 1-99 (45-90) wt.% of at least one olefin polymer; (b) 1-99 (10-30) wt.% of at least one polymer having a Tg above that of (A), and pref. above 75 deg.C, comprising (i) copolymers of a vinyl aromatic cpd. and an unsatd. dicarboxylic acid anhydride, imide, metal salt or partial ester of the dicarboxylic acid, or mixts.; (ii) terpolymers comprising a vinyl aromatic cpd. and an unsatd. dicarboxylic acid anhydride, imide, metal salt or partial ester of the dicarboxylic acid, or mixts., and a copolymerisable monomer; (iii) blends of reaction products of elastomer with (i) or (ii); (iv) blends comprising a polymer of vinyl aromatic cpd. and a polyarylene ether, and opt. an elastomer; (v) copolymers and terpolymers of a vinyl aromatic cpd. with acyclic ester and/or an alkyl-substd. acrylic ester; (vi) prod of the reaction of a di-alpha,beta-olefinically unsatd. carboxylic reagent and a hydrogenated block copolymer of a vinyl aromatic cpd. and an aliphatic conjugated diene: (vii) polycarbonate; (viii) graft copolymers of a monoethylenically unsatd. resin-forming monomer and a terpolymer of two different alpha-mono-olefins and non-conjugated dienes; (ix) acrylic polymers; (x) nitrile resins; (xi) acrylic-styrene-acrylonitrile polymers; (xii) acrylonitrile-halogenated polyolefin-styrene, terpolymers and mixts. of two or more of (i)-(xii); and (C) 1-40 (2-10) wt.% of an effective amt. of a compatibilising agent comprising a diblock, triblock, multiblock, starblock or graft block copolymer of a vinyl aromatic cpd. and a conjugated diene or its partially hydrogenated deriv., and mixts.</p> |
