| Popis: | Polyblock butylenoxide-siloxaneurethane elastomers with a specific chemical structure defined by a changed content of butylene oxide and dimethylsiloxane prepolymers with NCO terminal groups are prepared by a directed one-step synthetic procedure. The synthesis is carried out at room temperature in methyl ethyl ketone without catalysts and chain extenders using aromatic diamines as crosslinking agents. The proposed method allows one to obtain copolymers with a different structure. Such copolymers have high deformation and strength characteristics and are promising in medicine. |
