ABSTRACT:
The present invention is directed to mineral filled .alpha.-amino acid polymer composite materials. The composite materials are prepared by the in situ polymerization of an .alpha.-amino acid N-carboxyanhydride in the presence of mineral fillers which are optionally surface-modified with a partially hydrolyzed polyoxazoline prior to said polymerization. Composite materials prepared in this manner consist of an intimate mixture of polymer and mineral filler which may be optionally blended with a crosslinking agent and then molded to produce smooth, hard homogeneous materials that are water and oil resistant and have good heat distortion properties.
