    摘要: A silane or siloxane containing at least one organic group is prepared by a hydrosilylation reaction between a silane or siloxane (A) containing at least one Si—H group and an allyl compound (B) in the presence of a noble metal catalyst. The silane or siloxane (A) and the allyl compound (B) are fed continuously through a reaction zone which is maintained at a temperature in the range 115–200° C. and which is provided with heat exchanger means to dissipate the heat from the exothermic hydrosilylation reaction. The residence time of (A) and (B) in the reaction zone is less than 20 minutes.

    摘要: An amino-functional polysiloxane is prepared by reacting an aminosilane (A) which contains an aminoalkyl group and at least one alkoxy group bonded to Si with a carboxylic acid and a silanol-functional polysiloxane (B). The aminosilane (A) is partially converted into its carboxylate salt which acts as a catalyst for the siloxane condensation polymerization reaction between (A) and (B).

    摘要: An organopolysiloxane containing both an amino functional organic group and a mercapto functional organic group is disclosed. A method of making such amino-mercapto functional organopolysiloxanes is by reacting (A) a silanol-functional polysiloxane, (B) an amino functional alkoxy silane, and (C) a mercapto functional alkoxy silane, via a condensation reaction. The amino-mercapto functional organopolysiloxanes products are useful in textile and fabric treatments.
