FIELD: chemistry.
SUBSTANCE: method involves saturating nonwoven polymer materials, polymer netting or glass fibre with 20-55% solution of OKM-2 or PN609-21A polyether acrylate carbonate oligomer or a solution of ED-20 epoxide oligomer in ethyl alcohol, polymerisation of the oligomer and evaporating the solvent. Polymerisation is carried out at high temperature but not higher than melting point of the polymer, and while adding dicumyl peroxide to the solution in amount of 10% of the weight of the oligomer as a chemical polymerisation initiator or polymerisation is carried out with exposure to UV radiation in the presence of a photoinitiator - azodinitrile in amount of 0.5-0.8% of the weight of the oligomer. The polymerised oligomer must not dissolve in the given solvent.
EFFECT: membranes based on cross-linked oligomers have high strength, heat resistance and chemical resistance.
