Resin blends having improved toughness and resistance to heat deformation are obtained by blending crystalline propylene polymers, random thermoplastic styrenic copolymers containing α,β-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.
A method for minimizing power loss, reducing a fuel consumption and/or for reducing and/or avoiding deposits in a fuel system in the direct injection diesel engines. The method contains adding a copolymer to a fuel composition, wherein the copolymer contains, in a copolymerized form: (A) an ethylenically unsaturated mono- or dicarboxylic acid or a derivative thereof, (B) an α-olefin having from 12 to 30 carbon atoms, (C) optionally an additional aliphatic or cycloaliphatic olefin which has at least 4 carbon atoms and is different from monomer (B) and (D) optionally an additional copolymerizable monomers other than monomers (A), (B) and (C), anhydride or carboxylic acid functionalities present in the copolymer are partly reacted with at least one compound (E) comprising an alcohol group and/or an amino group, and the anhydride functionalities present in the copolymer are hydrolysed and/or carboxylic ester functionalities present in the copolymer are partly hydrolyzed.
