IMPACT MODIFIED POLYESTER BLENDS

摘要

IMPACT MODIFIED POLYESTER BLENDS Impact modified polyester blends are provided which are blends of a saturated polyester such as poly(ethylene terephthalate)and an impact modifying amount of a combination of a core-shell polymer and a copolymer of an alpha-olefin having 2 to 8 carbon atoms and a monomer selected from an unsaturated carboxylic acid having 3 to 8 carbon atoms and salts and anhydrides thereof. The polyester compositions of this invention are useful to mould into useful objects.
