<P>PROBLEM TO BE SOLVED: To provide an additional-cross-linkable material which is free from defects of the prior art and achieves improved usable time and cross-linking speed simultaneously. <P>SOLUTION: A platinum catalyst (D) of formula (I): R<SP>1</SP><SB>2</SB>Pt[P(OR<SP>2</SP>)<SB>3</SB>]<SB>2</SB>is used as a catalyst for a hydrosilylation reaction in order to hydrogenate unsaturated organic compounds or polymers and oligomerize alkynes and is used in an additional-cross-linkable composition. The additional-cross-linkable silicone composition can be produced economically from easily-available starting substances by a simple method and has excellent storage stability at 25°C and under ambient pressure. When the additional-cross-linkable silicone composition is a one-component silicone composition to be cross-linked quickly at raised temperature or a two-component silicone composition, the processability of the cross-linkable silicone composition after both components are mixed is kept over a long period of time at 25°C and under ambient pressure and has such a merit that it can not be cross-linked quickly up to the raised temperature. <P>COPYRIGHT: (C)2009,JPO&INPIT |
