专利号:US-11753503-B2 优先权日:2018-05-17 标 题:Supported onium salts as initiators for the synthesis of polycarbonates by copolymerization of CO2 with epoxides 发明人:FENG XIAOSHUANG; PATIL NAGANATHA; LUCIANI CAROLINE; GNANOU YVES; HADJICHRISTIDIS NIKOS 权利人:UNIV KING ABDULLAH SCI & TECH 摘要:Supported onium salts used as initiators for the synthesis of polycarbonates by copolymerization of carbon dioxide with epoxides are described. Embodiments of the present disclosure describe initiators comprising an insoluble portion including an onium cation attached to an insoluble support; and an anion, wherein the anion is a counter-ion to the onium cation. Embodiments further describe methods of making polycarbonates using the initiator, methods of making initiators, and the like.
专利号:US-8853350-B1 优先权日:2012-09-25 标题:Synthesis of polyoxometalate-loaded epoxy composites 发明人:ANDERSON BENJAMIN J 权利人:SANDIA CORP 摘要:The synthesis of a polyoxometalate-loaded epoxy uses a one-step cure by applying an external stimulus to release the acid from the polyoxometalate and thereby catalyze the cure reaction of the epoxy resin. Such polyoxometalate-loaded epoxy composites afford the cured epoxy unique properties imparted by the intrinsic properties of the polyoxometalate. For example, polyoxometalate-loaded epoxy composites can be used as corrosion resistant epoxy coatings, for encapsulation of electronics with improved dielectric properties, and for structural applications with improved mechanical properties.
专利号:US-8841473-B2 优先权日:2009-09-01 标题 :Synthesis of fluorosilicones and their derivatives 发明人:MARCINIEC BOGDAN; MACIEJEWSKI HIERONIM; DABEK IZABELA; KARASIEWICZ JOANNA 权利人:MARCINIEC BOGDAN; MACIEJEWSKI HIERONIM; DABEK IZABELA; KARASIEWICZ JOANNA; UNIV ADAM MICKIEWICZ 摘要:The subject of invention is the method of synthesis of fluorosilicone co-polymers of arbitrary topology and general formula 1 in which among others if A stands for CH—O(CH 2 ) m (CF 2 ) n CF 2 H group, then the method is based on hydrosilylation reaction of appropriate fluoroalkyl-allyl ether with polyhydrosiloxanes containing at least one Si—H group, catalyzed by siloxide rhodium complex. If A stands for in which Z stands for divalent group either then the method is based on the reaction of nucleophilic opening of oxirane ring in appropriate epoxyfunctional co-polysiloxanes, in acidic environment.
