AGRICULTURAL ITEMS AND AGRICULTURAL METHODS COMPRISING BIODEGRADABLE COPOLYMERS

摘要

2 agricultural article comprising a biodegradable polyhydroxyalkanoate copolymer comprising two randomly repeating monomer units. The first randomly repeating monomer units (i) R ¹ is H or C _1-2 alkyl and n is 1 or 2 having the formula; The second randomly repeating monomer units (ii) R ² has the formula of C _3-19 alkyl or C _3-19 alkenyl al. More than 50% of the random repeating monomer units have the formula of the first randomly repeating monomer unit.
