METHOD OF PREPARING ANISOTROPIC POLYMER SOLUTION TO FORM FILMS AND FIBERS Russian patent published in 1999 - IPC

Abstract RU 2136792 C1

FIELD: polymer materials. SUBSTANCE: liquid-crystal solutions of heterocyclic polymers suitable to form long high-strength heat-resistant fibers and films are provided, in particular, high-molecular poly(benzo[1,2-d:4,5d] bis-thiazole-2,4-diyl)- 1,4-phenylene in polyphosphoric acid with P2O5 level 85.5-86.5% additionally containing polyphosphoric acid with P2O5 level 72.4-72.8% or water. EFFECT: facilitated processing of anisotropic spinning solution due to reduced dynamic viscosity of polycondensation solution. 4 cl, 2 dwg, 1 tbl, 7 ex
