  • Patent number: 10358529
    Abstract: Particles are prepared in an emulsion using a method that includes providing a first reactant having at least two unsaturated carbon-carbon moieties and a second reactant having at least two Si—H moieties, so long as at least one of the unsaturated carbon-carbon moieties of the first reactant or the Si—H moieties of the second reactant is pendant. The method also includes providing a third reactant having a silicon atom and a condensable reactive group bonded to the silicon atom and also having an unsaturated carbon-carbon moiety and/or a Si—H moiety, providing a hydrosilylation catalyst, and providing a polar liquid. The method further includes combining the first, second, and third reactants to form particles that have a cross-linked network wherein the condensable reactive group is disposed on the particles, and adding a silane having an organic moiety and a condensation leaving group to form the particles.

  • Patent number: 9872828
    Abstract: An emulsion includes a liquid continuous phase and a dispersed phase including a cross-linked aminosiloxane polymer. The cross-linked aminosiloxane polymer includes a first siloxane backbone, a second siloxane backbone, and at least one intramolecular structure cross-linking a silicon atom of the first siloxane backbone and a silicon atom of the second siloxane backbone. The intramolecular structure has the chemical structure: (Formula (I)) wherein X is chosen from the following groups; (Formula (II); (Formula (III)); or (Formula (IV)) wherein each R is independently a C-1-C-10 hydrocarbon group, each R1 is independently a C-1-C-10 hydrocarbon group, each R2 is independently a hydrogen atom, OH, a C-1-C-12 hydrocarbon group, a phenyl group, R?(OR?)m wherein m is 1 to 3, or R?OH, wherein each of R? and R? is independently an alkyl group, and wherein a is 0 or 1. This disclosure also provides a method of forming the emulsion.

  • Patent number: 9868866
    Abstract: A hydrolysis resistant aqueous emulsion includes a hydrolyzable silicon containing compound. This emulsion is formed by a method that includes the step of (A) forming a seed emulsion that includes (1) an emulsifier, (2) water, and (3) a first oil phase. The method also includes the step of (B) adding a second oil phase, including a hydrolyzable silicon containing compound, to the seed emulsion. A weight ratio of the second oil phase including the hydrolyzable silicon containing compound to the first oil phase in the seed emulsion is from 0.5 to 50. Moreover, a total weight of the first and second oil phases in the emulsion is at least 60 weight percent.
