摘要：
A numerical solution of the problem of extraction of a low-molecular-weight solvent from a spherical polymer product with allowance for shrinkage is suggested. The solution is based on passage from a variable region to a fixed one using a difference scheme of a special form developed for the convective-diffusion equation in which the convection and diffusion terms vanish with time.
