Claims

1. IN A PROCESS OF REACTING A COMPOUND HAVING ALIPHATIC UNSATURATION AND BEING FREE FROM AMINO, ALDEHYDO AND RADICALS HAVING A CYANO GROUP ON AN UNSATURATED CARBON ATOM WITH A SILICON COMPOUND CONTAINING AT LEST ONE SILICON-BONDED HYDROGEN ATOM AND HAVING NOT MORE THAN TWO HYDROGEN ATOMS ATTACHED TO ANY ONE SILICON ATOM, IN THE PRESENCE OF A PLATINUM CATALYST, SAID SILICON COMPOUND BEING SELECTED FROM THE GROUP CONSISTING OF A SILANE OF THE GENERAL FORMULA RASIHBX4-A-B WHERE R IS A HYDROCARBON GROUP;

X IS SELCTED FROM THE GROUP CONSISTING OF HALOGEN, ALKOXY AND ARYLOXY;

A IS SELECTED FROM THE GROUP CONSISTING OF 0, 1 AND 2;

B IS SELECTED FROM THE GROUP CONSISTING OF 1 AND 2 AND A+B IS NOT GREATER THAN 4, A HYDROLYSIS PRODUCT OF SUCH A SILANE AND A COHYDROLYSIS PRODUCT OF SUCH A SILANE WITH ANOTHER HYDROLYZABLE SILANE, THE IMPROVEMENT WHICH COMPRIES USING AS THE PLATINUM CATALYST, A COMPLEX OF A PLATINOU HALIDE SELECTED FROM THE GROUP CONSISTING OF PLATINUM CHLORIDE AND PLATINOUS BROMIDE WITH AN OLEFIN SELECTED FROM THE GROUP CONSISTING OF ETHYLENE, PROPYLENE, BUTYLENE, CYCLOHEXENE AND STYRENE.
