  • Method for preparing polyorganosiloxanes by polymerization catalyzed by a catalytic system based on triflic acid or triflic acid derivatives
    Patent number: 6737495
    Abstract: The invention concerns a method for preparing polyorganosiloxanes (POS) by (a) condensation polymerisation of monosilanes and/or acyclic siloxanes bearing reactive Si—OR units with R═H, or alkyl, or by (b) redistribution/condensation polymerisation of siloxane compounds based on cyclosiloxanes and/or acyclic siloxanes capable of bearing reactive Si—OR units such as defined above, Si—H or Si-alkenyl units, in the presence of an acid catalyst.
    Type: Grant

  • Method for preparing polyorganosiloxanes by polymerisation catalysed by a catalytic system based of triflic acid derivatives
    Publication number: 20030109659
    Abstract: The invention concerns a method for preparing polyorganosiloxanes (POS) by (a) condensation polymerisation of monosilanes and/or acyclic siloxanes bearing reactive Si—OR units with R=H, or alkyl, or by (b) redistribution/condensation polymerisation of siloxane compounds based on cyclosiloxanes and/or acyclic siloxanes capable of bearing reactive Si—OR units such as defined above, Si—H or Si-alkenyl units, in the presence of an acid catalyst.
