Abstract
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.
