Abstract:
A composite resin material comprising:(a) a matrix of at least one of a nonreactive resin and a polymer alloy of said nonreactive resin with a rubber;(b) particles of a hydrolysis product of a crosslinked polyurethane resin having a melt viscosity at a kneading and molding temperature lower than the melt viscosity of said nonreactive resin, or said polymer alloy, at said kneading and molding temperature and wherein the crosslinks of said polyurethane resin are partly cut and partly maintained, the particles of said hydrolysis product being dispersed in said matrix; and(c) particles of a solid filler forming a core within the particles of said hydrolysis product,wherein each of said nonreactive resin and polymer alloy thereof is a resin which has no functional groups reactable with crosslinks of the crosslinked polyurethane resin or with active groups of the hydrolysis product resulting from hydrolysis thereof, and which is meltable by heating.
