Patent
CA 2618726
The invention relates to a hydrosilylation method consisting in mixing an unsaturated base polymer, a silane compound and a hydrosilylation catalyst with platinum comprising a masterbatch containing a polymer matrix having solid platinum dispersed therein. The invention is characterised in that the concentration of solid platinum in the mixture thus obtained is between 12 and 35 ppm and preferably between 12 and 20 ppm.
La présente invention concerne un procédé d' hydrosilylation consistant à mélanger un polymère de base insaturé, un composé silane et un catalyseur d' hydrosilylation au platine constitué par un mélange maître composé d'une matrice polymère dans laquelle est dispersé du platine solide. L'invention est remarquable en ce que la teneur en platine solide du mélange ainsi obtenu est comprise entre 12 et 35 ppm, et de préférence entre 12 et 20 ppm.
