摘要:
Compositions comprising a specific ethoxylated/propoxylated product as well as an alkylene carbonate, an epoxysilane or a polysiloxane are useful for dyeing or finishing fibrous materials. Reaction products formed from said products are also very useful for these purposes. Said products are preferably used as solutions in supercritical carbon dioxide.
摘要:
The present invention relates to a method for the preparation of a medical device element by means of extrusion or injection moulding and to medical devices comprising such extruded or injection moulded medical device elements. The medical device elements (e.g. tubes, wires, lines, stents, catheters, guides, endodontic instruments, needles, trocars for e.g. laparoscopic surgery, laparoscopic accessories, surgical instruments, guide wires) are characterized by a prefabricated shaped article or a thermoplastic substrate polymer having thereon a layer of a covalently cross-linked coating composition of a thermoplastic matrix polymer and a hydrophilic polymer. The method involves a coating composition comprising a thermoplastic matrix polymer, a hydrophilic polymer, and one or more photo-initiator(s), e.g. covalently linked to molecules of the thermoplastic matrix polymer and/or to molecules of the hydrophilic polymer. The coating composition is irradiated with UV or visible light so as to covalently cross-link said coating composition.
摘要:
An object of the present invention is to provide a novel copolymer capable of exerting excellent dispersibility to various kinds of cement including cement having low fluidity (difficult cement), and a dispersant for cement and cement composition including the copolymer. The copolymer of the present invention is a copolymer obtainable by polymerizing polymer components including an unsaturated (poly)alkylene glycol ether monomer (a), an unsaturated carboxylic acid monomer (b), and an unsaturated cross-linkable monomer (c) or an unsaturated polymerizable monomer (d).
摘要:
Lactone/alkylene oxide polymers are useful as demulsifiers to break emulsions, e.g. water-in-oil and oil-in-water emulsions, particularly oilfield emulsions. These polymers are random or block polymer made from addition reactions of a hydroxyl- and/or amine-containing base compound with at least one lactone monomer and at least one alkylene oxide monomer.

It is intended to provide polyethylene glycol derivatives having a saccharide residue-containing side chain and a carboxyl group-containing side chain and a process for producing the same. Moreover, drug delivery system carriers and gene transfer carriers containing these polyethylene glycol derivatives are provided.
摘要:
A method for processing decomposed reusable polyol, which method is used for processing the decomposed and recovered polyol obtained by decomposing polyurethane resin, and the decomposed reusable polyol obtained by the processing method. In the processing method, any of the following processes is selectively used: the process that after an organic dicarboxylic acid or anhydride thereof is added to the decomposed and recovered polyol containing the amines, the precipitate is removed; the process that an isocyanate compound is added to the decomposed and recovered polyol containing the amines; the process that an oxide compound is added to the decomposed and recovered polyol containing the amines; and the process that a urea is added to the decomposed and recovered polyol containing the amines.

A surfactant which is the reaction product of a hydrocarbyl-substituted succinic anhydride or a reactive equivalent thereof with at least one water-dispersible amine-terminated poly(oxyalkylene), is effective for use in soil remediation.
摘要:
A liquid, pourable 100% active rheological additive especially useful for thickening nonaqueous compositions is described. The additive, which exists in a pourable, pumpable form at up to a 100% as a rheologically active composition, exhibits excellent thickening efficiency for systems including inks, epoxies, polyesters, paints, greases and other systems, including ease of dispersibility, without adversely affecting gloss. The additive may operate by both an associative and a reaction mechanism to provide rheological viscosity properties to such systems, and is also similarly useful for aqueous systems. One important aspect of the present invention relates to a liquid rheological additive composition comprising a reaction product obtained from the reaction of:
a) One or more active hydrogen compounds, wherein the active hydrogen compound contains at least two active hydrogen moieties; and b) One or more compounds containing at least two moieties which are capable of reacting with the active hydrogen moieties of (a), wherein the active hydrogen moieties of compound a) are in stoichiometric excess of the reactive moieties of compound b); and the reaction product has at least two active hydrogen moieties at its termini.
