BIODEGRADABLE PLASTIC FOOD SERVICE ITEMS

摘要

A food service item comprises a biodegradable polyhydroxyalkanoate copolymer comprising two randomly repeating monomer units wherein the first randomly repeating monomer unit has the structure (i) wherein R<1> 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 R<2> is a C3-19 alkyl or a C3-19 alkenyl. At least about 50 % of the randomly repeating monomer units have the structure of the first randomly repeating monomer unit.
