TOUGHENED POLYESTER AND ARTICLES THEREFROM

摘要

Disclosed are polyester compositions comprising a polyester polymer, such as poly(lactic acid), and an impact modifier comprising a tubular reactor produced ethylene copolymer derived from monomers (a) ethylene; (b) one or more olefins of the formula where CH2=C(R1)CO2R2, where R1 is hydrogen or an alkyl group with 2-8 carbon atoms and R2 is an alkyl group with 1-8 carbon atoms, such as methyl, ethyl, or butyl; and (c) one or more olefins of the formula CH2=C(R3)CO2R4, where R3 is hydrogen or an alkyl group with 1-6 carbon atoms, such as methyl, and R4 is glycidyl.
