ABSTRACT:
Resin blends having improved toughness and resistance to heat deformation are obtained by blending crystalline propylene polymers, random thermoplastic styrenic copolymers containing .alpha.,.beta.-unsaturated dicarboxylic acid anhydride, and amino- or hydroxy-functionalized elastomers. The amino- or hydroxy-functionalized elastomers may be formed in situ by the reaction of anhydride-functionalized elastomers and linking compounds having at least two active-hydrogen containing functional groups such as amino or hydroxyl.
