ABSTRACT:
The present invention provides novel filament winding, hand lay-up, reaction injection molding, and pultrusion methods for producing novel articles. Each of the inventive methods utilizes a resin composition comprising a polyester base resin, a viscosity and flow improving agent, and a filler. The viscosity and flow improving agent comprises a phosphated polyester, said phosphated polyester being a saturated polyester having acidic groups. Using the inventive methods, articles having exceptionally high aluminum trihydrate loadings can be formed. These articles exhibit excellent flame resistance and smoke evolution properties.
