ABSTRACT:
An acrylic modifier composition for improving impact resistance of polyester compositions is provided which comprises (a) between about 10% to about 90% by weight of a first component selected from the group consisting of an ethylene alkyl acrylate co-polymer and ethylene alkyl methacrylate copolymer, wherein the alkyl is C1 to C10; and (b) between about 10% to about 90% by weight of a second component selected from the terpolymer group consisting of ethylene/alkylacrylate/ glycidyl methacrylate; ethylene/alkyl acrylate/glycidyl acrylate; ethylene/alkyl methacrylate/glycidyl acrylate; and ethylene/alkyl methacrylate/glycidyl methacrylate, wherein the alkyl is C1 to C10. Polyester compositions toughened by addition of the modifier composition are disclosed, as are articles molded from these compositions and processes for forming these polyester compositions.
