High-performance anisotropic plastics magnet and a process for producing the same

Claim 1

An anisotropic plastics magnet having a maximum energy product of at least 0.9 MGOe, a remanence of at least 2000 G and a coercive force of at least 1800 Oe, said magnet being comprised of: at least one ferromagnetic powder having a large magnetic anisotropy selected from the group consisting of: Mo.6fe 2 O 3 ferrite magnet powders, wherein M is selected from the group consisting of Ba, Sr and Pb, Rco 5 rare earth-cobalt magnet powders wherein R is at least one rate earth element selected from the group consisting of Sm, Pr, Ce, La and Y, manganese-bismuth magnet powders, and manganese-aluminum magnet powders; and at least one resin selected from the group consisting of: metal-cross-linked copolymers of α-olefin and α,β-unsaturated mono- or dicarboxylic acid selected from the group consisting of: ethylene-acrylic acid copolymer, ethylene-metacrylic acid copolymer, ethylene-acrylic acid-metacrylic acid copolymer, ethylene-acrylic acid-methacrylic acid methyl ester copolymer and ethylene-metacrylic acid-acrylic acid methyl ester copolymer, with said metal ion selected from the group consisting of: Na + , K + , Li + , Cn + , Be + + , Mg + + , Ca + + , Ba + + , Cu + + , Fe + + , Co + + , Ni + + , Zn + + , Al + + + , Sc + + + , Fe + + + and Y + + + , and a saponified resin of a copolymer of ethylene and vinyl acetate, the axis of the easy magnetization of said ferromagnetic powders being oriented substantially in one direction.
