摘要:
The present invention relates to a process for adding Si-bonded hydrogen to aliphatically unsaturated compounds containing carbon-carbon multiple bonds and ether oxygen atoms in the presence of carbinol groups, wherein the reaction mixture comprises, as a further component, at least one cyclic ether.
摘要:
Hydrophilic siloxane copolymers are prepared by (a) reacting organopolysiloxanes having at least one Si-bonded hydrogen atom with substantially linear oligomeric or polymeric compounds of formula R1-(A-CnH2n)m-A1-H (I) where R1 is a monovalent optionally substituted, hydrosilylatable hydrocarbyl radical, A is a bivalent polar organic radical selected from —O—, —C(O)—O—, —O—C(O)—, —O—C(O)—O—, —C(O)—NH—, —NH—C(O)—, urethane radicals and urea radicals, A1 is a bivalent polar organic radical selected from —O—, —NH— and —NR′—, n is an integer from 1 to 20, and m is zero or a positive integer, (b) reacting the resulting intermediate with organic compounds which have two or more isocyanate groups, in the presence of further organic compounds (6) reactive toward isocyanate groups and containing at least one tertiary amine group, and (c) quaternizing the amino-group-containing intermediate from step (b) with an alkylating agent (8), with the proviso that the water content of the compounds (1) and (2) is lower than 2000 weight ppm.

摘要:
Silicone polyethers are prepared in a two stage process by reacting an unsaturated polyether with a first Si—H functional organopolysiloxane and then with a second organopolysiloxane, in which the weight ratio of silicon bonded hydrogen in the first and second organopolysiloxanes is at least 0.9. The reaction is more rapid than a single step process and produces a product with less unreacted Si—H content.
摘要:
Defoamer compositions of high effectiveness containing at least one siloxane-based antifoam and polysiloxane copolymers obtained by coupling a polysiloxane bearing active-hydrogen-containing hydrophilic polymer moieties by means of a di- or polyisocyanate.
摘要:
Cellulosic substrates are treated with compound(s) containing at least two primary amino groups and compounds containing at least one β-ketocarbonyl group. The substrates exhibit good strength and hand properties.
摘要:
Organosilicon compounds containing β-ketoamide groups and organic polymer groups bound via enamine bonds are prepared by reaction of compounds bearing at least one β-ketocarbonyl functionality with organosilicon compounds bearing aminoalkylaminoalkyl groups. The products have the same uses as siloxanes containing polyether and acetoacetate groups.
