摘要： The present invention provides oral care compositions for treating tooth sensitivity. The composition comprises a synergistic mixture containing a copolymer having at least one repeating unit of alkyl vinyl ether functionality and a monomer having at least one repeating unit of ethylenically unsaturated dicarboxylic acid or anhydride functionality present in an amount of about 0.1 to about 50% (w /w) of the total mixture; and a homo polymer having repeating unit of alkyl vinyl ether functionality present in an amount of about 0.1 to about 50% (w / w) of the total mixture. These synergistic mixtures of polymers act as barriers for dentin flow and reduce pain and discomfort caused by tooth sensitivity and exhibits at least 60% average reduction in dentin flow.

摘要： An antimicrobial polymer stable to aqueous hydrolysis contains a phenolic antimicrobial agent covalently bounded to one or more polymerized ethylenically unsaturated monomer units, preferably through an imide and/or amide group The phenol group is permanently covalently bonded to the main chain of the biocidal polymer through a stable imide and/or amide bond The polymer prevents microbial colonization in or on a substrate material, e g a building material, such as a shingle or gypsum board, while also killing fungi on its surface, or plastics, e g polyvinyl chloride materials, and can be delivered alone or with a drug in a delivery system.

摘要： Stable water based High-Temperature-High-Pressure (HTHP) and/or Non-HTHP crosslinked copolymers for oil and gas applications consist of (i) a crosslinked, linear polyvinyl amide/polymerizable carboxylic acid) copolymer, having a composition, by weight, of 25-75 wt. % of a vinyl amide monomer selected from vinyl pyrrolidone, vinyl caprolactam, N-vinyl-N-methylacetamide and mixtures thereof, and 25-75 wt. % of a polymerizable carboxylic acid monomer selected from acrylic acid, (meth)acrylic acid, crotonic acid, itaconic acid, maleic acid and mixture thereof; and (ii) a crosslinker in an amount of 0.01-5% based on weight of total monomers. Also discloses relevant compositions comprising said copolymer and method of use thereof.
