FIELD: chemistry of polymers.
SUBSTANCE: elastomer-modified epoxide-polysiloxane compositions proposed by the invention are prepared by combining a silicon-containing intermediate compound with epoxy resin, elastomeric resin-like intermediate compound, polyfunctional amine, optional metalloorganic catalyst and optional filling agents, pigments and technological additives. Composition is prepared in using amount of water sufficient for stimulation of complete hydrolysis of polysiloxane and for polycondensation of silanols obtained as result of this hydrolysis. Epoxide-polysiloxane in its hardened form shows dispersed cross-linked arrangement wherein either one of two or both components of epoxide and/or polysiloxane polymers are modified with elastomer. Prepared covers show significantly improved features with respect to shock-resistance, bending, resistance against cracking and stability in abrasion as compared with usually used epoxide systems.
EFFECT: improved and valuable properties of compositions.
