POLYMER COMPOSITION Russian patent published in 1995 - IPC

Abstract RU 2028337 C1

FIELD: polymer compositions. SUBSTANCE: polymer composition contains, mas.part: fatty aromatic polyimide 100; copper sulfate or copper silicate or their mixture in ratio of from 1:99 to 99:1, and if need be, additionally 0.5-50 mas.part of polycarbonate, polysulfonate or fluorine-containing polymer or copolymer; 0.005-0.2 of heat-resistant filler. Material based on the polymer composition losses 12.5% of its mass after thermal aging at 250 C in the air for 1000 h, tensile strength loss at 200 C for 15 days 2.4%: melt flow index 2.0 at 320 C, pressure 10 kg and holding time of 10 min. EFFECT: higher efficiency. 3 cl, 1 tbl
