Title:
不均一系ヒドロシリル化触媒、この触媒により形成されるポリマー、および関連のコーティング組成物
Document Type and Number:
Japanese Patent JP2009529409
Kind Code:
A
Abstract:
Disclosed are heterogeneous platinum group metal catalysts that are catalytically active towards hydrosilylation. These catalysts include a carrier in communication with platinum group metal particles, wherein the particles are affixed to a polyelectrolyte layer. Also disclosed are polymers that are the hydrosilylation reaction product of (a) a polysiloxane containing silicon hydride and (b) an organic compound having aliphatic unsaturation in the molecule, wherein the hydrosilylation reaction is carried out in the presence of a catalytic amount of such a catalyst, a heterogeneous platinum group metal catalyst that is catalytically active towards hydrosilylation, coating compositions that include such polymers and substrates at least partially coated with such compositions.
