A polyamide is produced by polymerizing at least one of an alpha, beta-unsaturated carboxylic acid and ammonia, an ammonium salt of an alpha, beta-unsaturated carboxylic acid, an alpha, beta-unsaturated nitrile and water, a beta-amino propionic acid or alkyl derivative thereof and an alpha, beta-unsaturated amide and ammonia in the presence of a catalyst comprising a pentaammine cobalt (III) complex.

Polyamide preparation with pentaamine cobalt (III) complex catalyst

Polyamides can be formed in good yields by the copolymerization of at least one alpha, beta-unsaturated nitrile with at least one alpha, beta-unsaturated carboxylic acid or ammonium salt thereof. These polymers are suitable for use as fibers, plastics, films and molding resins.

Process for the preparation of polyamide from unsaturated nitrile and

Polyesteramides can be prepared by copolymerizing a cyclic lactone with at least one of an ammonium salt of an alpha, beta unsaturated monocarboxylic acid, an alpha, beta unsaturated nitrile and water and beta-aminopropionic acids and their alkyl derivatives. Polymers with especially good physical properties were prepared by polymerizing caprolactone with one or more ammonium methacrylate, ammonium acrylate, acrylonitrile and beta-alanine. These polymers are useful as molding plastics.

Process for the preparation of polyesteramide from cyclic lactone

Polyamides can be formed in good yields by the copolymerization of at least one alpha, beta-unsaturated nitrile with at least one amino acid. These polymers are suitable for use as fibers, plastics, films and molding resins.

Nylon preparation from unsaturated nitrite with amino acid

This invention relates to a new process for preparing a copolyamide comprising polymerizing an alpha, beta-unsaturated nitrile and water with a molar excess of a lactam. In one embodiment, acrylonitrile, water and caprolactam are polymerized to form a nylon-3,6.
