  • Patent number: 11859079
    Abstract: An aliphatic epoxy resin precursor composition containing an epoxy component and, optionally, a reactive component, the composition containing no phenols, wherein the epoxy component is a glycerol-based ether, and wherein the precursor composition contains greater than about 60% (w/w) of the epoxy component and between 0% and 30% (w/w) of the reactive component. A cured aliphatic epoxy resin containing a precursor composition and a curing component, the precursor composition including an epoxy component and, optionally, a reactive component, and the cured resin containing no phenols, wherein the epoxy component is a glycerol-based ether, and wherein the precursor composition contains greater than about 60% (w/w) of the epoxy component and between 0% and 30% (w/w) of the reactive component.

  • Patent number: 6046293
    Abstract: A process for manufacturing high molecular weight, alternating polysiloxane copolymers, by solid-liquid phase, nonaqueous, interfacial polymerization. The copolymers consist of alternating siloxane repeating units of the (AB).sub.m type, such as diphenylsiloxane units and dimethylsiloxane units, alternately polymerized together to form the copolymer. The solid-liquid phase interfacial polymerization process is fast, proceeds smoothly at room temperature, and is not reversible, i.e., no cyclic siloxane species are generated. The resulting polysiloxanes can be formed into thermoplastic elastomers which are suitable for use as sealants, fillers, and films.

  • Patent number: 5969173
    Abstract: Dialkali metal organosilanolate and dialkali metal organosiloxanolate salts are manufactured from cyclic siloxanes or linear silicone polymers using a heterogeneous interfacial reaction process. A stoichiometric excess of an alkali metal hydroxide such as potassium hydroxide or an alkali metal oxide as a solid or dissolved or dispersed in a compatible solvent, is prepared and used as a first phase. The cyclic siloxane or linear silicone polymer is placed in a second phase either dissolved or dispersed in another solvent which is immiscible with the first phase. The resulting silanolate and siloxanolate salts can be used as monomers for solid-liquid phase and liquid-liquid phase interfacial polymerization or in a polycondensation process for the synthesis of alternating siloxane polymers. They can also be used as ring opening initiators for the base catalyzed polymerization of cyclic siloxanes.
