Abstract:
1. A method for the preparation of a polyamide-based composition comprising particulate silica substantially uniformly dispersed into a polyamide matrix, the method comprising: first mixing at least one polyamide-producing monomer with water to form a reaction mixture and then adding more than 2 weight percent particulate silica to the reaction mixture to form a suspension wherein the particulate silica is substantially uniformly dispersed therein; then polymerizing the at least one polyamide-producing monomer with the particulate silica substantially uniformly dispersed in situ to provide a polyamide matrix wherein the particulate silica remains substantially uniformly dispersed in the resulting polyamide matrix to form the polyamide-based composition.
