Which of the following statements about biodegradable polymers are correct?
ANylon 2-nylon 6 has amide linkages that can be hydrolysed.
BPHBV has ester linkages that can be hydrolysed.
CPolythene is biodegradable because its C−C backbone is readily cleaved by water.
DComplete hydrolysis of PLA gives lactic acid.
Answer: A, B, D
Amide and ester links are hydrolysable, and PLA is a polyester of lactic acid. Polythene has an all-carbon backbone with no hydrolysable link, so it is not readily biodegradable.
