摘要

A mathematical description of interconnected processes of mass transfer and chemical conversion in a copolymerization reactor is given. Two cases are investigated: simultaneous transfer of two monomers from a gas to a liquid with chemical reaction in the liquid (for example, copolymerization of ethylene and propylene in ethylene-propylene synthetic rubber production) and copolymerization in a liquid near a solid surface (for example, copolymerization of isobutylene and isoprene in butyl rubber production). The dependence of the component composition of the copolymer on the diffusion resistance to the transfer of monomers near the interface is established.
