(ii) Glycine + amino caproic acid
(iii) Ethylene glycol + phthalic acid
(iv) Caprolactum

Solution
(i) 3-hydroxybutanoic acid + 3-hydroxypentanoic acid
(ii) Glycine + amino caproic acid
Explanation:
Poly β-hydroxybutyrate – co-β-hydroxy valerate (PHBV) It is obtained by the copolymerisation of 3-hydroxybutanoic acid and 3 - hydroxypentanoic acid. PHBV is used in speciality packaging, orthopaedic devices and in controlled release of drugs. PHBV undergoes bacterial degradation in the environment.
Nylon-2nylon 6: It is an alternating polyamide copolymer of glycine \[\ce{H2N - CH2 - COOH}\] and aminocaproic acid \[\ce{[H2N(CH2)5COOH]}\] and is biodegradable.
