Biodegradable copolymers and plastic articles comprising biodegradable copolymers of 3-hydroxyhexanoate

摘要

The present invention relates to biodegradable PHA copolymers comprising at least two randomly repeating monomer units (RRMU) wherein the first RRMU has the structure wherein R1 is H or C2 alkyl, and n is 1 or 2; the second RRMU has the structure and wherein at least 50% of the RRMUs have the structure of the first RRMU. The present invention further relates to plastic articles comprising said biodegradable PHA copolymers. The present invention further relates to an absorbent article comprising a liquid pervious topsheet, a liquid impervious backsheet comprising a film comprising a PHA of the present invention and an absorbent core positioned between the topsheet and the backsheet.
