METHOD OF MAKING MEMBERS MADE OF POLYCAPROLACTAM Russian patent published in 1995 - IPC

FIELD: polymeric compounds. SUBSTANCE: process is carried out in the opened capacity. Metallic sodium is added at solution stirring at vortical regime of back and rotary motion of stirring member. Prepolymer is added to mixture and dissolved at stirring. Mixture viscosity is operated before attainment of ratio of initial mixture liquid flow rate v_o to the final value v_к up to the value v_o/v_к 1:2. In the process of members made of filled polycaprolactam after attainment of mixture liquid viscosity value v_o/v_к 1: 1.5 filler is added to the liquid. EFFECT: improved method of member making. 2 cl, 1 tbl
