    Abstract: The present invention is aimed at a series of novel glycerin polyesters that provide desired aesthetics and structure in cosmetic formulation. These glycerin polymers are synthesized by polycondensation polymerization, in the presence of a monofunctional monomer or terminal group. By carefully choosing the groups the properties can be dramatically altered. The mono-functional alcohols, being only able to react in one position, can only be located on the polymer chain ends. This provides very unique polymer structure and morphology. These regiospecific polyesters will have very unique physical properties and have a wide variety of solubilities. Furthermore, by the incorporation of a co-monomer will produce a copolymer with drastically different solubilities and aesthetics.

  • Patent number: 8796484
    Abstract: A polymerizable dimethicone copolyol macromer composition is synthesized by reacting itaconic anhydride with a dimethicone copolyol. During the reaction itaconic anhydride spontaneously isomerizes to citraconic anhydride which in turn is esterified by the dimethicone copolyol. The obtained macromers are copolymerizable with olefinically unsaturated monomers. Polymers containing the macromer repeating units are useful in a variety of applications including personal care, textile and industrial formulations to deliver softness, lubricity, fixative, water repellency, gloss, surface modification, and surfactant properties.

  • Patent number: 8722837
    Abstract: A composition is prepared by oxidative copolymerization of specific amounts of 2,6-dimethylphenol, 2,3,6-trimethylphenol, and a hydroxyaryl-terminated polysiloxane. The composition exhibits an increased heat resistance relative to a corresponding composition prepared by copolymerizing 2,6-dimethylphenol and hydroxyaryl-terminated polysiloxane, without 2,3,6-trimethylphenol. The composition is useful as a flame-retardant additive in polymer compositions that require high heat resistance.

  • Patent number: 8680225
    Abstract: The present invention is directed toward a series of polyglycerol polyesters that have silicone terminal groups with tunable ascetics and performance in cosmetic formulation. These novel silicone containing polyglycerol polyesters are designed to be multidimensional. Multidimensional is meant that the polymer contains a variety of groups containing different chemical and physical properties covalently bonded together. The physical properties of the current invention can be tuned rapidly by controlling the ratio of fatty groups, as well as the cross-linker used. Tuned here is meant the ability to adjust the physical properties to a desired value. The resulting polyglycerol polyesters have outstanding aesthetics and physical properties.

  • Patent number: 8669332
    Abstract: A thermoplastic composition that includes a poly(arylene ether)-polysiloxane block copolymer is prepared by a method that includes oxidatively copolymerizing a monohydric phenol and a hydroxyaryl-terminated polysiloxane. The oxidative polymerization includes a monohydric phenol addition period characterized by a first temperature, a build period following the addition period and characterized by a second temperature greater than the first temperature, and a temperature ramp period between the addition period and the build period. During the temperature ramp period, the temperature is increased at an average rate of about 0.01 to about 0.35° C. per minute, which improves the efficiency with which the hydroxyaryl-terminated polysiloxane is incorporated into the poly(arylene ether)-polysiloxane block copolymer.
