NYLON 6 Usage And Synthesis

Chemical Properties

crystalline powder

Uses

Nylon-6, a condensation polymer, can be produced by chainwise, ring openings of cyclic amide (lactam) without expulsion of small molecules, and also by stepwise polycondensation of #>amino acid.

Uses

NYLON 6 is a commonly known synthetic material used as a fiber in eyelash lengtheners and mascaras, and as a molding compound to shape cosmetics. NYLON 6 gives bulk to a formulation and, when appropriate, provides opacifying properties. It can cause allergic reactions.

Uses

Tire cord; fishing lines; tow ropes; hose manufacture; woven fabrics.

Definition

NYLON 6 is a type of synthetic polymer linked by amide groups –NH.CO–. NYLON 6 polymers can be made by copolymerization of a molecule containing two amine groups with one containing two carboxylic acid groups.

Safety Profile

Moderately toxic by ingestion. Mildly toxic by inhalation. Questionable carcinogen with experimental neoplastigenic data by implant route. When heated to decomposition it emits toxic fumes of NOx.

Solubility in organics

o-Chlorophenol, m-cresol
