    • 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. SOLUTION: A platinum catalyst (D) of formula (I): R 1 2 Pt[P(OR 2 ) 3 ] 2 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.

    • 要解决的问题:提供一种没有现有技术缺陷的附加交联材料,并同时实现改善的可用时间和交联速度。 解决方案:式(I)的铂催化剂(D):R(SP)1 Pt / P(OR SP> 2< SP> > 3> 用作氢化硅烷化反应的催化剂,以氢化不饱和有机化合物或聚合物并使炔烃低聚并用于另外的可交联组合物中。 可以通过简单的方法从容易获得的起始物质经济地制备另外的可交联硅氧烷组合物,并且在25℃和环境压力下具有优异的储存稳定性。 当另外的可交联硅氧烷组合物是在升高的温度下快速交联的单组分硅氧烷组合物或双组分硅氧烷组合物时,将两种组分混合后的可交联硅氧烷组合物的加工性能保持在 在25℃和环境压力下长时间的使用,具有不能快速交联升温的优点。 版权所有(C)2009,JPO&INPIT
