A series of differently crosslinked macroporous 2,3-epoxypropyl methacrylate-ethylenedimethacrylate copolymers with chemically bonded propylsulphonic acid groups were used as catalysts for the kinetic study of reesterification of ethyl acetate by n-propanol in the liquid phase at 52 °C and in the gas phase at 90 °C. Analysis of kinetic data by the method of nonlinear regression for a series of equations of the Langmuir-Hinshelwood type showed that kinetic equations which describe best the course of the reaction are the same as for the earlier studied sulphonated macroporous styrene-divinylbenzene copolymers. Compared types of catalysts differ, however, in the dependence of their activity on the degree of crosslinking of the copolymer used.

The paper considers the features of modification of wood (pine) with reactive copolymers based on glycidyl methacrylate and fluorine (alkyl) methacrylates to impart water-repellent properties. Such modification provides the achievement of superhydrophobic properties and a decrease in the water permeability of the material due to a smaller spot of contact of water drops with the surface. Wood water absorption index reduced by 3 times.
