BIODEGRADABLE COPOLYMERS AND PLASTIC ITEMS THAT INCLUDE BIODEGRADABLE COPOLYMERS OF 3-HYDROXIHEXANOATE.

摘要

THE PRESENT INVENTION REFERS TO AHP BIODEGRADABLE COPOLYMERS THAT INCLUDE AT LEAST TWO MONOMERIC UNITS REPEATED RANDOMLY (UMRR) WHERE THE FIRST UMRR HAS THE STRUCTURE (I) WHERE R {SUP, 1} IS HO RENT, C {2} YN IS 1 OR 2, THE SECOND UMRR HAS THE STRUCTURE (II) AND WHERE AT LEAST 50% OF THE UMRRS HAVE THE STRUCTURE OF THE FIRST UMRR. THE PRESENT INVENTION FURTHER REFERS TO PLASTIC ARTICLES THAT INCLUDE THESE BIOLEGRADABLE AHP COPOLYMERS. THE PRESENT INVENTION ALSO REFERS TO AN ABSORBENT ARTICLE THAT INCLUDES A LIQUID PERMEABLE UPPER LAYER, A LIQUID WATERPROOF REAR LAYER THAT UNDERSTANDS A FILM THAT INCLUDES A AHP OF THE PRESENT INVENTION AND A ABSORBENT NUCLEAR POSITIONED ABOVE.
