Accepted Answer

>

> [!TLDR]
> Neoprene is a synthetic rubber made by polymerising chloroprene; nylon-6 comes from the self-condensation of caprolactam, while nylon-6,6 is a condensation copolymer of hexamethylenediamine and adipic acid.
>
> **a) i) Example of a synthetic rubber**
>
> Neoprene (polychloroprene) — a vulcanisable, rubber-like synthetic elastomer.
> (Other valid examples: Buna-N, Buna-S/SBR.)
>
> **a) ii) Preparation of neoprene**
>
> Neoprene is prepared by the free-radical polymerisation of chloroprene (2-chloro-1,3-butadiene):
>
> n CH2=CCl–CH=CH2 (chloroprene) --(free radical polymerisation)--> (–CH2–CCl=CH–CH2–)n (Neoprene)

> **b) Monomers of Nylon-6 and Nylon-6,6**
>
> - Nylon-6: formed by the self-condensation (ring-opening polymerisation) of a SINGLE monomer, caprolactam, under heating. …
