  • Glass-clear nylons from 3,3'-dimethyl PACM
    Patent number: 4264762
    Abstract: A glass-clear nylon based on aromatic dicarboxylic acids and dialicyclic diamines is prepared by polycondensing isophthalic acid with a mixture of 3,3'-dimethyl-4,4'-diamino-dicyclohexylmethane and hexamethylenediamine.The nylons may be used for the production of moldings, especially by injection-molding.

  • Polyhexamethylene adipamide molding compositions not subject to discoloration when conditioned with water
    Patent number: 3970634
    Abstract: Molding compositions based on polyhexamethylene adipamide and containing phenolic additives and, to obviate discoloration on conditioning, from 0.001 to 0.5% by weight, based on polyhexamethylene adipamide, of a compound having a chain transfer constant for styrene at 100.degree.C of more than 1.5. The preferred chain transfer agent used is n-dodecylmercaptan.
