  • Dimethylsiloxane-alkylene oxide copolymers
    Patent number: 11642304
    Abstract: Copolymers are formed of monomers of poly(dimethylsiloxane) and poly(alkylene oxide) of the following formula: Ax-XCH2CH2—[ByCz]n—X-Ax. In the formula, each X independently represents a —CH2— group or an oxygen atom, A represents a polydimethylsiloxane derivative, B represents a polyethylene glycol unit, C represents a polypropylene glycol unit, x and n independently represent an integer from 1 to 150, and y and z independently represent an integer from 0 to 150. The copolymers can be used as emulsifiers in personal care compositions.

  • Oligomeric (TH)FP, production and uses therefor
    Patent number: 10358430
    Abstract: A method for the isolation of oligomeric 2, 2-difurylpropane (DTHFP) suitable for use on an industrial scale. A method can include using oligomeric 2, 2-difurylpropane, in particular, its use can be as a polar modifier for butadiene and styrene butadiene polymerization so is to produce rubber. Utilizing the material as an alternative to DTHFP in rubber production avoids subsequent leaching of the DTHFP into the environment as the oligomeric 2, 2-difurylpropane (DTHFP) gives rise to much lower levels of leaching.

  • Chelate-controlled diastereoselective hydrogenation with heterogeneous catalyst
    Patent number: 10000460
    Abstract: A hydrogenation catalyst, preferably palladium on a support, preferably alumina or activated charcoal support, is used in the presence of lithium salts, with salts such as the borates being preferred. This provides hydrogenation of precursors to give rise to a stereoselective, such as diastereoselective bias in the product of alkene hydrogenation using the catalyst.
