摘要： The invention provides a hydrophilized polydiorganosiloxane vinylic crosslinker which comprises (1) a polydiorganosiloxane polymer chain comprising dimethylsiloxane units and hydrophilized siloxane units each having one methyl substituent and one monovalent C4-C40 organic radical substituent having two to six hydroxyl groups, wherein the molar ratio of the hydrophilized siloxane units to the dimethylsiloxane units is from about 0.035 to about 0.15, and (2) two terminal (meth)acryloyl groups. The hydrophilized polydiorganosiloxane vinylic crosslinker has a number average molecular weight of from about 3000 Daltons to about 80,000 Daltons. The present invention is also related to a silicone hydrogel contact lens, which comprises repeating units derived from a hydrophilized polydiorganosiloxane vinylic crosslinker of the invention.

摘要： A composition includes at least one siloxy-based (meth)acrylate monomer or prepolymer, at least one additional methacrylate monomer, UV, and Visible light blocking agents and one or more crosslinking agents. The final product results in a highly wettable material that possesses physical properties such as a low modulus of elasticity and high oxygen permeability without the need for a non-reactive solubilizing agent and that are free of cyclic and linear siloxanes.

摘要： Polymer matrix composite comprising a porous polymeric network; and a plurality of intumescent particles distributed within the polymeric network structure; wherein the intumescent particles are present in a range from 15 to 99 weight percent, based on the total weight of the intumescent particles and the polymer (excluding the solvent); and wherein the polymer matrix composite volumetrically expands at least 2 times its initial volume when exposed to at least one temperature greater than 135° C.; and methods for making the same. The polymer matrix composites are useful, for example, as fillers, thermally initiated fuses, and fire stop devices.

摘要： A single-screw extruder for changing a morphology of a superabsorbent polymer, specifically a polymer gel. The single-screw extruder has an input aperture, a channel, a screw and an output aperture. The screw has a pitch value of a pitch of the screw flights along the conveying zone of the channel, where the channel has a mixing-element arrangement with at least one mixing element which protrudes into the channel of the single-screw extruder and which is configured for the mixing of the SAP polymer gel.

摘要： Provided is an agent for dispersing an electrically conductive carbon material, in which the agent consists of a polymer which has an oxazoline group in a side chain and which is obtained by using an oxazoline group-containing monomer such as that represented by formula (1) for example, and in which the agent exhibits excellent dispersion of an electrically conductive carbon material and produces a thin film that exhibits excellent adhesion to a current collection substrate when formed into a thin film together with the electrically conductive carbon material. (In the formula, X denotes a polymerizable carbon-carbon double bond-containing group, and R1-R4 each independently denote a hydrogen atom, a halogen atom, an alkyl group optionally having a branched structure having 1-5 carbon atoms, an aryl group having 6-20 carbon atoms, or an aralkyl group having 7-20 carbon atoms.)
