MATHEMATICAL MODELING OF POLYMER FILM CASTING UNDER BIAXIAL STRETCHING TAKING INTO ACCOUNT HEAT TRANSFER

摘要

Polymer film casting is studied using a modified Vinogradov-Pokrovskii rheological model with heat transfer taken into account. Dependences of the film temperature, velocity, and width on the distance to the extruder exit was obtained and the effect of model parameters on these dependences was examined.
