  • Publication number: 20020132129
    Abstract: The present invention relates to an aqueous emulsion polymer which is useful as a woodworking adhesive. The polymer is prepared by reacting vinyl acetate with an N-methylol containing copolymerizable monomer in the presence of polyvinyl alcohol wherein at least 85% of the polyvinyl alcohol is hydrolyzed and a water-dispersible nonionic polyurethane. The polyurethane is prepared by reacting (i) an organic polyisocyanate, (ii) water-soluble polyalkylene glycols containing at least 70 weight percent of ethylene glycol units, and (iii) polyhydric branched alcohols containing at least three hydroxyl groups per molecule.

  • Patent number: 6395800
    Abstract: The biocompatibility of various polymers are improved by blending with them a polymer including a zwitterionic group. The zwitterionic group is usually an ammonium phosphate ester zwitterionic group and the polymer containing it may be produced by the free radical polymerisation of ethylenically unsaturated monomers including a monomer bearing the zwitterionic group. Blending of the two polymers may be achieved by dry blending particulate polymers or by mixing the polymers in liquid dispersion or solution followed by removal of the liquid medium. The fibrinogen absorption and/or platelet activation of polymers may be reduced to a value of less than 80% or even less than 60% of the base polymer by introducing amounts of more than 10% or more than 30% of the zwitterionic group containing polymer. Preferred blends are of copolymers of 2-(methacryloyloxyethyl)-2′-(trimethylammonium)ethyl phosphate inner salt with higher alkyl(meth)acrylate, blended with olefin polymers and/or with rubber latices.

  • Patent number: 6387998
    Abstract: The invention relates to a process for preparing a cationically modified (meth)acrylamide polymer by the Mannich reaction. There is prepared in advance a stable aldehyde-secondary amine adduct, which is obtained as a reaction product of an aqueous solution of the secondary amine and an aqueous solution of the aldehyde, and which, after the formation of the adduct, is stabilized to endure storage, by lowering the pH of the mixture of 7 or below and/or by adding methanol, and the adduct thus prepared is added to an aqueous solution of the (meth)acrylamide polymer and the pH is adjusted to an alkaline level, whereupon modification occurs. The invention also relates to the use of the modified (meth)acrylamide polymer as a flocculation, retention or dewatering agent.

  • Patent number: 6228931
    Abstract: A low-solvent aqueous binder includes: a water-insoluble synthetic resin component A; and an emulsifier resin B in a mass ratio of A to B of from 70:30 to 30:70. The emulsifier resin B is a reaction product of a water-insoluble synthetic resin B1 that includes hydroxyl groups as functional groups, a synthetic resin B2 that includes carboxyl groups as functional groups, and a neutralizing agent for the carboxyl groups of B. The amount of the neutralizing agent is such that the neutralizing agent is able to neutralize from 5 to 200% of the carboxyl groups of B. A process for preparing a low-solvent aqueous binder includes: mixing the water-insoluble synthetic resin component B1 comprising hydroxyl functional groups and the synthetic resin B2 in bulk or dissolved in an organic solvent to form a mixture; removing the solvent by applying subatmospheric pressure and heating until the content of the mixture is at least 85% by mass; maintaining the mixture at a temperature from 90° to 150° C.

  • Patent number: 6207265
    Abstract: A water soluble, non-ionic masking agent is used in the manufacture of printed circuit boards. The masking agent masks portions of the circuit board to prevent adhesion of solder, flux and the like. The masking agent includes a water soluble non-ionic binder resin, a cellulosic non-ionic filler, a non-ionic surfactant, at least one non-ionic associative thickener, and deionized water. The masking agent material is readily removed from the circuit board after manufacture and does not render further wash water processing ineffective. The masking agent is non-ionic, and thus does not agglomerate or clump downstream ion-exchange or filtration media.
