  • Publication number: 20180362404
    Abstract: Conventional methods suffer from unsatisfactory performance of the dehydration-preventing agent at a high temperature, and the present invention provides a cement admixture exhibiting an excellent dehydration-preventing effect at a high temperature. The cement admixture of the present invention includes a crosslinked product of a modified polyvinyl alcohol-based resin, wherein the dissolution rate of 1 g of the crosslinked product of a modified polyvinyl alcohol-based resin for 1 liter of water at 70° C. is 50% or less.

  • Patent number: 10111421
    Abstract: Disclosed is a dispersing agent for agrochemicals, said dispersing agent which comprises a modified polyvinyl alcohol-based resin containing a structural unit having a nonionic hydrophilicity group in side chain, and having a saponification degree of 95 mol % or more. The dispersing agent for agrochemicals can provide a dispersion in which a hardly water-soluble agrochemical active ingredient employed for a dispersoid is dispersed in a stable state even in the case where the dispersoid has a relatively large particle size.

  • Patent number: 9809697
    Abstract: An object of the invention is to provide a crosslinking agent with which a crosslinked polymer that suffers little coloring with the lapse of time and shows excellent viscosity stability is obtained. The crosslinking agent of the invention includes a compound which contains two or more alkylhydrazide groups represented by the following general formula (1). (In formula (1), R1 represents an alkyl group having 1-10 carbon atoms, and symbol * is a linking bond.
