3- 3- FILMS AND ABSORBENT ARTICLES COMPRISING A BIODEGRADABLE POLYHYDROXYALKANOATE COMPRISING 3-HYDROXYBUTYRATE AND 3-HYDROXYHEXANOATE

摘要

The present invention relates to a film comprising a biodegradable copolymer, wherein at least two random repeating monomer units are characterized in that the first RRMU monomer has the following structural formula (a) and the second RRMU monomer has the following structural formula (b) (RRMU), wherein at least 50% of the RRMUs have a structure of a first RRMU. The present invention also relates to an absorbent material comprising a liquid permeable topsheet, a biodegradable liquid impermeable backsheet containing the film, and an absorbent core positioned between the topsheet and the backsheet.;(a);(b)
