FIELD: polymer chemistry.
SUBSTANCE: invention relates to synthesis of oligomers and copolymers. Described is a polymer for making articles for space purposes, obtained from a mixture of organosilicon oligomer-polymer bicarbonate and its prepolymer (oligomer) and terminating substituted mono-cyanate of phenol. Said mixture is cured with a metal complex or a transition metal salt. Copolymers are obtained with a triazine structure with alternation of bisphenol and siloxane structures and with terminating mono-cyanate-phenol components in a single polymer, having shape memory effect at different temperatures depending on ratio of bisphenol cyanide or its prepolymer (oligomer) and organosilicon oligomer-polymer dicyanate.
EFFECT: technical result is high polymer resistance to ionizing radiation, oxidation by atomic oxygen, temperature drops and other destructive factors of outer space.
