Abstract RU 2097395 C1

FIELD: building materials. SUBSTANCE: chrysotile asbestos is subjected for wet grinding with boric acid addition at its ratio to amount of brucite excess in asbestos = (0.35-1):1 and dried. Polymeric composition exhibits the improved properties: bending strength - at parent state is 1256-1258 kg/cm2; after 100 h at 400 C - 604-606 kg/cm2; impact viscosity after 100 h at 400 C - 19 kg/cm2; spiral fluidity is 725-740 mm. EFFECT: improved method of producing, improved properties. 1 tbl
