The reaction of hybrid polyaddition of dihydroorganocyclotetra (penta, hexa)siloxanes to divinylorganocyclopenta(hexa)siloxanes in the presence of 0.01 M H2PtCl6ยท6H2O solution in tetrahydrofuran has been investigated. The rate constant and activation energy of the polyaddition reaction were calculated. It was established that with an increase in cycle volume, the rate of polyaddition decreases. Thermomechanical and X-ray analyses of amorphous copolymers were conducted as well as thermogravimetric investigations were performed with simultaneous analysis of gaseous products of the reaction. It was shown that with an increase in the volume of cyclic fragments, thermal stability of copolymers decreases. |
