    摘要: Blends of metallic, preferably ferromagnetic, particles, macrocyclic oligomer compositions, especially poly(alkylene dicarboxylate) oligomers, and catalysts/initiators for polymerization of said macrocyclic oligomers are molded into magnets having high metal loadings, typically about 60-85% by volume. Compression molding of such blends can be conducted at relatively low pressures.

    摘要: A method for producing a unitary part having a property enhancing coating strongly bonded to a core of either plastic or fiber reinforced composite is provided by applying the coating to a formed and shaped carrier substrate which is placed into the mold. Plastic is injected into the mold such that the plastic infiltrates the coating during molding and therefore locks the coating to the part after cure. Utilizing the present method substantially enhances the coating bond strength and reduces manufacturing costs by eliminating a post production coating step.
