Abstract
A thermoplastic blend of a polyalkylene terephthalate, polyolefin and a functionalized elastomer has improved impact strength while maintaining other needed properties including tensile strength, tensile elongation, and flexural modulus. Recycled polypropylene and PET plastics can be combined with a relative small amount of the functionalized elastomer to provide a blend useful for molding battery containers and other plastic structural members such as automotive components.
