Abstract

A polyamide moulding composition comprises superpolyamide granules coated with from 0,005 to 0,1% by weight based on the weight of the granules of a monoamide or ethylenebis-amide of a monocarboxylic acid containing 12 to 20 carbon atoms. Specified polyamides are polyhexamethylene adipamide, polyhexamethylene sebacamide, polycaprolactam and copolymers of hexamethylene diamine with adipic acid, sebacic acid and caprolactam. Specified monocarboxylic acid amides are lauramide palmitamide, myristamide, stearamide, 1, 2-ethylene - bis - stearamide, 1, 2 - ethylenebis - mynstamide and 1, 2 - ethylene - bis palmitamide. The compositions may be prepared by dry-blending. The examples describe the coating of polyhexamethylame adipamide granules with 1, 2 - ethylene - bis - stearamide and the moulding of the resultant compositions. Specifications 461,236 and 461,237 are referred to.ALSO:A polyamide moulding composition comprises superpolyamide granules coated with from 0.005 to 0.1% by weight based on the weight of the granules of a monoamide or ethylene-bis-diamide of a monocarboxylic acid containing 12 to 20 carbon atoms.
