  • Patent number: 8912299
    Abstract: This invention relates to a method for preparing a star-shaped polycarboxylate superplasticizer by the first esterification step with polyol and (meth)acrylic acid as main reactants and the second polymerization step. In the first step, the star-shaped polymerizable active ends were synthesized by esterification between polyol and (meth)acrylic acid in the presence of catalyst. In the second step, the final star-shaped polycarboxylate superplasticizer was prepared by radical polymerization among the product obtained in first step, unsaturated polyoxyethylene ethers, molecular weight regulator and unsaturated carboxylic acid in the presence of initiator. The production process of this invention exhibits some characteristics including simple, easily controllable, high polymerization degree, low cost and pollution free. The star-shaped molecular structure of polycarboxylate superplasticizer can be achieved through synthesizing active “core” by esterification and “arm” by radical polymerization.

  • Patent number: 7009011
    Abstract: A stable free radical process for preparing a polymer having acid anhydride functionality includes heating a mixture comprised of a stable free radical agent, maleic anhydride or derivative thereof, and at least one polymerizable electron donor monomer to initiate exothermic reaction and during exotherm of the reaction, adding additional amounts of stable free radical agent to control the reaction temperature. The mixture may also include a stable free radical initiator. In the mixture, the maleic anhydride or derivative thereof preferably comprises from about 10% to about 70%, molar basis, of a total amount of the maleic anhydride or derivative thereof and the at least one polymerizable electron donor monomer. Typically, the heating is to a temperature of from about 100° C. to about 160° C., and the rate of addition of the additional amounts of stable free radical agent is adjusted to control the reaction temperature to be about 160° C. or less.

  • Patent number: 6995221
    Abstract: A process for producing organic peroxide initiators useful in the polymerization of ethylenically unsaturated monomers. The process for making the organic peroxides includes forming an aqueous emulsion of the organic peroxide. The organic peroxide is dispersed as small droplets of from 1 to 10 microns in size in the aqueous emulsion. The organic peroxide may be added to a polymerization reactor containing an ethylenically unsaturated monomer. The organic peroxide functions as a free radical initiator to polymerize the monomer. The organic peroxide may be substantially free of organic solvents and plasticizers. The resulting polymers are of high quality.

  • Patent number: 6946528
    Abstract: The invention provides a hot melt adhesive composition including a tubular reactor copolymer of ethylene and 5 to 20 mol % of comonomer units derived from an alkyl acrylate or alkyl methacrylate, wherein the copolymer has a melt index of at least 300 g/10 min. The alkyl group of the alkyl acrylate or alkyl methacrylate can be a linear or branched C1 to C12 group, particularly n-butyl. If desired, the hot melt adhesive can further include tackifiers, waxes, antioxidants and other desired additives. The hot melt adhesive composition shows improved heat resistance and favorable properties, such as has a shear adhesion fail temperature of at least 80° C., without the need to use high melting waxes. The invention further provides articles such as cartons, cases, trays, bookbindings or disposables including the hot melt adhesive compositions.

  • Patent number: 6930141
    Abstract: An aqueous polymer blend composition including a predominant amount of soft polymer particles and a minor amount of hard polymer particles is provided. The soft polymer particles contain, as copolymerized units, 70 to 99.7% by weight monoethylenically unsaturated (meth)acrylic monomer and from 0.3 to 10% by weight monoethylenically unsaturated acid monomer, based on weight of soft polymer particles. The soft polymer particles are made by a select process including redox polymerization or polymerization in the presence of excess unreacted monomer. The aqueous polymer blend composition is useful for preparing dry coatings having improved dirt pickup resistance and acceptable scrub resistance. A method is provided for preparing a dry coating from the aqueous polymer blend composition.
