  • Patent number: 4417032
    Abstract: A process for preparing quasi-random copolymers is described which involves heating a mixture of polyamides in the presence of one or more phosphite promotor(s). The process is conducted at temperatures between about 265.degree. C. and 315.degree. C. with the process time generally ranging from about 2 to about 20 minutes. The process is especially useful for preparing copolymers from a mixture of poly(caproamide) and poly(hexamethylene adipamide). The copolymer products prepared in accordance with the process are particularly suitable for the production of plastic films which have improved properties as compared to either of the homopolymers.
