ABSTRACT:
A process is provided for stabilizing thermoplastic particles with organic phosphite particles. The process involves applying a liquid, relatively low molecular weight, phosphite to the surface of thermoplastic particles. The particles exhibit hydrolysis compared to conventional phosphite shell/polymeric core structures. The particles may be molded into useful thermoplastic articles.
