DIPHASE SOLUTION OF METHYLMETHACRYLATE-METAACRYLIC ACID COPOLYMER FOR TREATING METALLIC SURFACES Russian patent published in 1998 - IPC

FIELD: chemistry of polymers. SUBSTANCE: present invention describes agent for preliminarily polishing metallic surface, said agent includes 1.0 % diphase conservatory copolymer solution containing 73-80 wt.% of methacrylic acid and 20-27 wt.% of methyl methacrylate having molecular weight of 800,000. Due to using diphase copolymer solutions as corrosion inhibitor and wear product sorbent, quality of surface and accuracy of shape formation thereof are obtained due to highly reflective surface. EFFECT: improved quality of the surfaces. 3 ex, 3 tbl
