标 题:Methods for synthesis of graft polymers
发明人：GAUTHIER MARIO; YUAN ZHONGSHUN
权利人:UNIV WATERLOO
摘要:A process for the synthesis of arborescent polymers comprises epoxidation of a first polymer and grafting thereto a second polymer having groups reactive to the epoxide groups on the first polymer. The epoxidation and grafting steps can be repeated. In an additional embodiment, the present invention provides a one-pot method for the synthesis of arborescent polymers. In a reaction pot, a first polymer is copolymerized and then reacted with an activating compound in order to generate a polyfunctional macroinitiator. Monomers are then added to the reaction pot, the monomers having functional groups reactive towards reactive sites on the first polymer.

摘要:A process for synthesis of finely divided antiperspirant suspensions includes providing an antiperspirant salt consisting essentially of an Al salt which is effective as an antiperspirant and which is described by an empirical formula as follows: Al(OH)( 3−b) X b zH 2 O where b=0.4 to 3, z<4, and X=halogen; mixing the Al salt into a non-aqueous oil phase to provide a mixture; and subsequently grinding the mixture with a suitable milling device at a temperature below 80° C. to provide a suspension having a preselected fineness. A perspiration-inhibiting cosmetic preparation includes, as active ingredient, the antiperspirant suspension described above.

标 题 :Process for the continuous synthesis of a modified diene elastomer
发明人：DORATO MARGARITA; FLESINSKI LIONEL
权利人:MICHELIN & CIE
摘要:A process for the continuous synthesis of a modified diene elastomer includes:n polymerization by n reactors r1 to rn equipped with an internal stirring system, the reactor r1 being fed by an input solution comprising a solvent, one or more monomers, an anionic polymerization initiator and a polar agent, one or more of the reactors being fed by reinjection of a purified solution comprising solvent and/or monomer(s), the number of dead chains in the output stream from the reactor rn is less than 30% of the number of living chains initiated in the reactor r1, the temperature of each reactor varying from 20° C. to 150° C.; and modification of the living diene elastomer obtained in the preceding stage and exhibiting a polydispersity index varying from 1.1 to 2, making it possible to introduce, into the elastomer, a functional group comprising at least one silicon atom directly connected to the elastomer chain.

标题:Flow controlled synthesis of bottlebrush macromolecules
发明人：GUIRONNET DAMIEN S; WALSH DYLAN J
权利人:UNIV ILLINOIS
摘要:Shape, size and composition are nature's most fundamental design features, enabling highly complex functionalities. Despite recent advances, the independent control of shape, size and chemistry of macromolecules remains a synthetic challenge. Herein reported is a scalable methodology to produce large well-defined macromolecules with programmable shape, size and chemistry that combines reactor engineering principles and controlled polymerizations. Specifically, bottlebrush polymers with conical, ellipsoidal and concave architectures are synthesized using two orthogonal polymerizations. The chemical versatility is highlighted by the synthesis of a compositional asymmetric cone. The strong agreement between predictions and experiments validate the precision that this methodology offers.

标 题:Topical application of immixture of ascorbic acid + ascorbic acid compounds for augmenting the synthesis of epidermal ceramides
发明人：CASTIEL ISABELLE; FERRARIS CORINNE; LAVALLE-BOUCHARD ARMELLE
权利人:OREAL
摘要:Synergistic immixtures of ascorbic acid with at least one monosaccharide ester of ascorbic acid and/or at least one metal salt of phosphorylated ascorbic acid more effectively increase the synthesis of epidermal ceramides in human skin, especially types IV to VII ceramides, as well as improve the barrier function, moisture content and/or suppleness/surface appearance of the skin and which otherwise combat/prevent intrinsic aging thereof and are useful for the treatment of dermatitis.
