Abstract
A glass bead-filled resin composition comprising (I) a thermoplastic polyurethane derived from polybutylene terephthalate and a polyfunctional isocyanate, (II) glass beads having a diameter of not more than 100 microns, and (III) an aminosilane or epoxysilane. The above composition can be prepared by kneading under heat (I) a thermoplastic polyurethane derived from polybutylene terephthalate and a polyfunctional isocyanate, and (II) glass beads having a diameter of not more than 100 microns and coated with (III) an aminosilane or epoxysilane.
