| 摘要 |
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.
