PDMS (vinyl group content of 10 mol% and a number-average molecular weight of 500,000 g/mol) and a chloroplatinic acid solution (as a catalyst) were obtained from the Research Center of Organic Silicone of Chengdu, China.
For the cross-linking reactions, addition reactions between silicon-hydrogen and vinyl group are carried out among the SR-FVI, the PDMS, and the HSO under the catalytic effect of chloroplatinic acid.
These oligomers are double-bond-functional silicones which become polymerized by free radicals from chloroplatinic
The most common platinum catalyst is chloroplatinic
acid (Speier's catalyst) which is reduced to a platinum (0) species in the presence of a silane or siloxane.

acid-catalyzed reaction of 1-tecradecene with a polysiloxane prepolymer was studied to discover optimal reaction conditions and determine the kinetics of the reaction.
The catalyst is a solubilized platinum complex of chloroplatinic
acid or alternatively a peroxide.
In the presence of chloroplatinic
acid, the hydrosilation reaction takes place between the two groups:
