摘要

An agricultural item comprising a biodegradable polyhydroxyalkanoate copolymer comprising two randomly repeating monomer units. The first randomly repeating monomer unit has the structure (i) wherein R1 is H or a C1-2 alkyl, and n is 1 or 2; and the second randomly repeating monomer unit has the structure: (ii) wherein R2 is a C3-19 alkyl or a C3-19 alkenyl. At least 50 % of the randomly repeating monomer units have the structure of the first randomly repeating monomer unit.
