    Abstract: Disclosed is cross-linking process for cross-linking polymeric chains in a coating composition. In one embodiment the process utilizes a Hantzsch dihydropyridine reaction to form reaction products including cross-linking polymeric resin chains having beta-keto ester functions using a source of aldehyde and a source of ammonia or a primary amine to form a permanent dihydropyridine bond between the beta-keto ester functions. The novel cross-linking reaction can occur at lower temperatures compared to typical cross-linking reactions and can occur in aqueous solutions that have a neutral to mildly alkaline pH of from 6 to 11. The novel cross-linking reaction provides many advantages to performing cross-linking of polymeric chains in coating resins.

Alternatively, the functional group on the grafted chain can react with a modifying agent to provide another group that can react with or interact with the target compound. The grafted chains are attached to the solid support through a ring-opened azlactone group. The articles can be used to purify the target compound or to separate the target compound from other molecules in a sample.

  • Patent number: 8546492
    Abstract: The present invention provides a surface treatment method for a water-absorbing resin comprising three steps of: 1) a humidifying and mixing step for mixing a base polymer and a surface cross-linking agent solution to obtain a “humidified substance”; 2) a pretreatment step for raising temperature of said humidified substance to obtain a “pretreated substance”; and 3) a surface cross-linking reaction step for cross-linking said pretreated substance to obtain a surface cross-linked “water-absorbing resin”; wherein dew point in the pretreatment step of the above 2) is from 50° C. to 95° C., and temperature of said humidified substance is raised from temperature below the dew point up to a temperature of 10° C. higher than the dew point.

  • Patent number: 8404785
    Abstract: A method for producing a modified conjugated diene polymer includes a step (A) carrying out a primary modification reaction that reacts a heterocumulene compound having two or more specific functional groups with a conjugated diene polymer having a vinyl content of below 10% and a cis-1,4-bond content of 75% or more and possessing an active end to obtain a primary-modified conjugated diene polymer, and a step (B) carrying out a secondary modification reaction that reacts an active hydrogen-containing compound that includes one or more functional groups selected from the group consisting of an amino group, an imino group, a mercapto group, and a hydroxyl group with the primary-modified conjugated diene polymer to obtain a secondary-modified conjugated diene polymer. The method can produce a modified conjugated diene polymer that exhibits low heat build-up (low fuel consumption) and excellent wear resistance.

    Abstract: A polymeric polymer is prepared from poly(oxyethylene)-amine and a linker, for example, poly(styrene-co-maleic anhydride) (SMA) or dianhydride. The polymeric polymer can chelate silver ions and reduce them to silver atoms which are dispersed as nanoparticles. No additional reducing agent is needed and more than 30% of solid content of the nanoparticles solution can be achieved without aggregation. The prepared silver nanoparticles are both hydrophilic and hydrophobic and therefore are compatible with polymers.
