On the mathematical modeling of mechanochemical degradation of acrylonitrile–α-methyl styrene–vinyl acetate terpolymer in conditions simulating the wet-spinning

This article aims to carry out mathematical modeling of the mechanochemical degradation process of acrylonitrile–α-methyl styrene–vinyl acetate ternary copolymer in conditions that simulate its wet-spinning from dimethyl formamide solution. The influence of some factors on the mechanochemical degradation process is studied. Based on a great number of experiments a regression equation is determined, which correlates the intrinsic viscosity of the copolymer solution with the mechanical process variables (the length and length/diameter ratio, solution concentration, and pressure).
