| abstract |
The invention relates to the reaction products (i) obtained by mixing at least one organohydrogensilicon compound containing at least one silicon-bonded hydrogen per molecule with at least one compound having at least one aliphatic unsaturation in the presence of a platinum group metal containing catalyst, at least one terminal A mixture comprising a blocking agent (ii) and, optionally, at least one organosiloxane (iii) selected from hydrolysates and cyclosiloxanes, is heated in the presence of a catalyst to form components (i), (ii) and, optionally, component (iii) ) Is polymerized to form a branched polymer. |
