THE PRESENT INVENTION RELATES TO BIODEGRADABLE PHA COPOLYMERSCOMPRISING AT LEAST TWO RANDOMLY REPEATING MONOMER UNITS. THE PRESENTINVENTION FURTHER RELATES TO A PLASTIC ARTICLE COMPRISING A BIODEGRADABLECOPOLYMER, WHEREIN THE BIODEGRADABLE COPOLYMER COPOLYMER COMPRISES AT LEAST TWO RANDOMLY REPEATING MONOMER UNITS (RRMU) WHEREIN THE FIRST RRMU HAS THE STRUCTURE(FORMULA)WHEREIN R1 IS H, OR C1 OR C2 ALKYL, AND N IS 1 OR 2; THE SECOND RRMU HAS THESTRUCTURE(FORMULA)AND WHEREIN AT LEAST 50OF THE RRMUS HAVE THE STRUCTURE OF THE FIRST RRMU. 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.
