REGULARITIES OF NONISOTHERMAL CRYSTALLIZATION IN THE FORMATION OF A PLANE VISCOELASTIC FILM

A study is made of the processes of heat transfer and nonisothermal crystallization during the formation of a plane viscoelastic polymer fi lm with the upper-convected Maxwell model, in which the thermophysical properties, viscosity, and relaxation time of the polymer depend on its temperature and the degree of crystallinity. The mathematical model is supplemented with the equation of nonoisthermal-crystallization kinetics. The problem is solved by the fi nite difference method
