METHOD OF PORE FORMING OF REQUIRED PARAMETERS IN CHEMICALLY STABLE POLYMERIC MATERIAL Russian patent published in 1998 - IPC

Abstract RU 2109769 C1

FIELD: polymers. SUBSTANCE: invention relates to preparing highly thermostable polymeric material of required structure and complex properties which can be used for separation of technological liquid components in food industry. Method involves addition of finely dispersed ferromagnetic vehicle to solution or melt of polymer and composition applying on forming surface followed by effect of magnetic field on composition and hardening for structure fixing. Then composition is subjected for acid effect up to pores formation from dissolved vehicle particles. EFFECT: improved method of forming, enhanced effectiveness of composition. 1 tbl
