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.
This prepolymer is reacted in a subsequent polycondensation at ambient or reduced pressure and temperatures of about 250 °C to higher molecular weight polyamide 12 ( PA 12: -[NH-(CH 2) 11-CO] n-). [11] As a comonomer, laurolactam is used together with ε-caprolactam for the preparation of copolyamide 6/12. [12]
Nylon is a family of synthetic polymers characterized by amide linkages, typically connecting aliphatic or semi-aromatic groups.. Nylons are generally white or colorless [1] [failed verification] [2] [failed verification] and possess a soft texture, with some varieties exhibiting a silk-like appearance.
Polyamides can also be synthesized from dinitriles using acid catalysis via an application of the Ritter reaction. This method is applicable for preparation of nylon 1,6 from adiponitrile, formaldehyde and water. [4] Additionally, polyamides can be synthesized from glycols and dinitriles using this method as well. [5]
