TIN CATALYST DERIVED FROM A CARBOXYLIC ACID AND A TIN BISCHELATE, AND ITS USE IN AN ELASTOMERIC COMPOSITION |
摘要 |
<p>A process for the preparation of a monochelate of pentacoordinated tin of valency IV by reaction of a tin bischelate and of an organic acid. The monochelate or the reaction mixture containing it can be employed as a catalyst for crosslinking an organopolysiloxane composition curing by polycondensation reactions and containing an alpha , omega -dihydroxypolydiorganopolysiloxane oil, a crosslinking agent and optionally inorganic fillers and an adhesion promoter. </p> |
