    摘要: A drycleaning method is disclosed. The method uses a composition comprising 30 to 90 wt. % of a dipropylene glycol C3-C4 alkyl ether, 5 to 65 wt. % of one or more C10-C15 hydrocarbons, and 1 to 10 wt. % of water. The method combines acceptable stain removal with faster-than-expected evaporability, particularly at the elevated temperatures used in commercial drycleaning.

    摘要: A comb-branched polymer is disclosed. The polymer comprises recurring units of an unsaturated carboxylic monomer, an oxypropylene-rich poly(oxyethylene-oxypropylene) macromonomer and an oxyethylene-rich poly(oxyethylene-oxypropylene) macromonomer. The comb-branched polymer can be used as a water reducing agent in cement. It gives significantly lower air entrainment in cement admixture.

    摘要: A gypsum composition containing a sulfonate-containing comb-branched copolymer is disclosed. The sulfonate-containing comb-branched copolymer comprises recurring units of a polyether macromonomer, an acrylic monomer, and a sulfonate monomer. The sulfonate-containing comb-branched copolymer not only increases the fluidity of gypsum slurry but also has reduced retardation on the gypsum setting.
