摘要: Embodiments include degradable polyethers comprising ester units from a cyclic ester or carbonate units from carbon dioxide incorporated into a poly(ethylene oxide) backbone or a multifunctional core of a degradable polyether star. Embodiments include methods of forming a degradable polyether comprising contacting an ethylene oxide monomer with a lactide monomer or carbon dioxide in the presence of an alkyl borane and an initiator. Embodiments include methods of forming degradable polyether stars comprising contacting a diepoxide monomer with carbon dioxide and/or a cyclic ester in the presence of an initiator and a first amount of an alkyl borane to form a multifunctional core comprising degradable carbonate linkages and/or degradable ester linkages, and contacting the multifunctional core with an ethylene oxide monomer in the presence of a second amount of an alkyl borane to form arms of a polyether attached to the degradable multifunctional core.

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.

摘要: The present invention concerns a metal or metal alloy deposition composition, particularly a copper or copper alloy deposition composition, for electrolytic deposition of a metal or metal alloy layer, particularly for electrolytic deposition of a copper or copper alloy layer, comprising at least one type of metal ions to be deposited, preferably copper ions, and at least one imidazole based plating compound. The present invention further concerns a method for preparation of the plating compound, the plating compound itself and its use in a metal or metal alloy deposition composition. The inventive metal or metal alloy deposition composition can be preferably used for filling recessed structures, in particular those having higher diameter to depth aspect ratios.

摘要: A mixture of two alkoxylates surfactants, one being an aryl aliphatic carbinol alkoxylate, the other one being a dialiphatic carbinol alkoxylate, said mixture being useful for stabilizing emulsions and dispersions used in agricultural or pharmaceutical formulations. The alkoxylates surfactants may serve as substitutes for nonylphenol ethoxylates (NPE) and tristyrylphenol ethoxylates (TSE).

摘要: The present invention relates to a method for manufacturing a hyperbranched polyester polyol derivative, comprising the following steps: a) reacting only glycidol and ε-caprolactone at a temperature lying in a range of between 40 °C and 140 °C to obtain a hyperbranched polyester polyol in which caprolactone residues are randomly arranged; b) reacting the hyperbranched polyester polyol of step a) with a sulfation reagent to obtain a sulfated hyperbranched polyester polyol as hyperbranched polyester polyol derivative. Aspects of the invention relate to a hyperbranched polyester polyol derivative obtainable by this method as well as uses thereof.
