An aliphatic rubbery synthetic polymer with the formula (C 4 H 6 O 2) n, it belongs to the polyvinyl ester family, with the general formula −[RCOOCHCH 2]−. It is a type of thermoplastic . [ 1 ]
Nylon 12 exhibits properties between short chain aliphatic nylons (e.g., nylon 6 and nylon 66) and polyolefins. [3] At 178-180 °C, the melting point of nylon 12 is the lowest among the important polyamides. Its mechanical properties, such as hardness, tensile strength, and resistance to abrasion, are similar to those of nylon 6 and nylon 66.

[11] [12] Polyacrylamide is of low toxicity but its precursor acrylamide is a neurotoxin and carcinogen. [1] Thus, concerns naturally center on the possibility that polyacrylamide is contaminated with acrylamide. [12] [13] Considerable effort is made to scavenge traces of acrylamide from the polymer intended for use near food. [1]

Repeating unit of polyphthalamide. Polyphthalamide (aka.PPA, [1] High Performance Polyamide) is a subset of thermoplastic synthetic resins in the polyamide family defined as when 55% or more moles of the carboxylic acid portion of the repeating unit in the polymer chain is composed of a combination of terephthalic (TPA) and isophthalic (IPA) acids.
