FIELD: chemistry.SUBSTANCE: invention relates to method of obtaining recyclised butyl ion-containing polymer. Method of obtaining recyclised butyl ion-containing polymer includes: a) supply of non-hardened initial butyl ion-containing polymer, which has tensile strength at the temperature of the environment; b) heating said initial butyl ion-containing polymer to temperature from 80 to 200°C; c) placement of initial butyl ion-containing polymer under conditions of mixing with high shift tension for at least 10 seconds; and d) cooling initial butyl ion-containing polymer, obtained at stage c), to the temperature of the environment with obtaining recyclised butyl ion-containing polymer. Thermally reversible product, made from non-hardened butyl ion-containing polymer, is also claimed.EFFECT: recyclised polymers demonstrate good preservation of properties.16 cl, 12 tbl, 57 ex |
