Detailed Solution
Glycine ($H_2N-CH_2-COOH$) and aminocaproic acid ($H_2N-(CH_2)_5-COOH$) form nylon-2-nylon-6, an alternating polyamide copolymer that is biodegradable.
Styrene + butadiene gives Buna-S, acrylonitrile + butadiene gives Buna-N and ethylene glycol + terephthalic acid gives dacron; these are not biodegradable.
