标 题 :Hydrophilic surface modification of polydimethylsiloxane
发明人：DHRUV HARSHIL; BRITT DAVID
权利人:UNIV UTAH STATE
摘要:A method for the preparation of hydrophilic elastomers involves the synthesis of polydimethylsiloxane with tunable hydrophilic surface properties. An elastomeric monolith with desired hydrophilic properties is produced by combining a polyethylene oxide polymeric surfactant additive with a PDMS base and curing agent during polymerization. The surfactant chain segment lengths are varied to control the hydrophobic/hydrophilic balance.

摘要:A silicone - (meth)acrylate - polyether copolymer includes a linear siloxane backbone with pendant (meth)acrylate - polyether moieties. The siloxane backbone is made up of a silicone moiety having a silicon bonded mercapto-alkyl linker (wherein the alkyl group in the linker is bonded to a silicon atom in the silicone moiety). The pendant (meth)acrylate - polyether moiety is covalently bonded to a sulfur atom in the mercapto-alkyl linker. The pendant (meth)acrylate - polyether moiety includes a (meth)acrylate - poly(alkylene glycol) unit. The silicone - (meth)acrylate - polyether copolymer is useful as a surfactant, formulation aid, and/or dispersant. The silicone - (meth)acrylate - polyether copolymer may be useful as a defoamer for coatings, oil and gas applications and/or pulp and paper applications. Furthermore, the silicone - (meth)acrylate - polyether copolymer may be useful as an additive for adjusting adhesion and/or release force in paper coatings such as pressure sensitive adhesive and/or release coating compositions.

标 题 :Deprotection method and resin removal method in solid-phase reaction for peptide compound or amide compound, and method for producing peptide compound
发明人：IWASAKI KOTARO; KOMIYA SHIO
权利人:CHUGAI PHARMACEUTICAL CO LTD
摘要:The present inventors found that peptide compounds/amide compounds in which the protecting groups of interest are removed and/or which are removed from resins for solid-phase synthesis can be produced without main chain damage by contacting starting peptide compounds/amide compounds with silylating agents.
