Abstract
An improved thermoplastic nylon molding resin comprising intimately mixed nylon molding resin and glass reinforcing agents in the presence of polyethylene terephthalate resin.
Claims6
An improved thermoplastic molding resin comprising a synthetic linear polyamide polymer having a relative viscosity in the range of from about 35 to about 100;
- from about 5 to about 60 weight percent based on the total composition of glass fiber reinforcing agent;
- and from about 1.0 to about 50 weight percent based on the total resin weight of polyethylene terephthalate.
A process for producing an improved thermoplastic molding resin wherein a synthetic linear polyamide polymer having a relative viscosity in the range of from about 35 to about 100 is intimately mixed with about 5 to about 60 weight percent of the total molding composition of glass fiber reinforcing agent and from about 1.0 to about 50 weight percent based on the total resin of polyethylene terephthalate having an intrinsic viscosity of from about 0.2 to about 1.0 dl/g.
