2201 results about "Hydrosilylation" patented technology

A composition for personal, home, or laundry treatment comprising a polymer made up of one or more crosslinked rake or comb silicone copolymer segments. A process for making copolymers for use in such compositions involves hydrosilylation in the presence of a catalyst.

Disclosed herein are manganese, iron, cobalt, or nickel complexes containing terdentate pyridine diimine ligands and their use as efficient and selective hydrosilylation catalysts.

A primer composition for a fluorinated elastomer or a fluorinated gel, said primer composition comprising:100 parts by weight of (a) a linear perfluoro polyether compound having at least two alkenyl groups per molecule, a perfluoro polyether backbone having repeating units represented by the formula, —CaF2aO—, wherein a is an integer of from 1 to 6, and a weight average molecular weight of from 5,000 to 100,000,(b) an organosiloxane compound having one or more fluorine atom and at least two SiH bonds per molecule, in such an amount that a molar ratio of the SiH bond in the organosiloxane compound to the alkenyl group in Component (a) ranges from 0.8 to 5.0,a catalytic amount of (c) a hydrosilylation catalyst,5 to 100 parts by weight of (d) an organosiloxane compound having, per molecule, at least one SiH bond and at least one epoxy group and / or trialkoxysilyl group bonded to a silicon atom of said organosiloxane via an organic group which may have an oxygen atom, and100 to 10000 parts by weight, per total 100 parts by weight of said components (a), (b), (c) and (d), of (e) an organic solvent having a fluorine atom and a boiling point of not higher than 150° C. at atmospheric pressure.

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 formulaR1-(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.
