ABSTRACT:
Disclosed is a polymer powder cross-linked by metallic ions and containing reinforcing material which includes a polymer cross-linked by metallic ions, and at least one reinforcing material selected from the group consisting of a fibrous reinforcing material and a particulate reinforcing material and contained uniformly in the polymer cross-linked by metallic ions in an amount of from 3 to 70% by volume. The polymer powder can be processed into a composite material based on the polymer. The composite material is improved in the strength and the impact resistance while maintaining the superb physical properties of the polymer, because the reinforcing material is dispersed too uniformly to be localized therein. Additionally, processes are disclosed which are suitably adapted to produce the polymer powder and the composite material.
