摘要： The present invention provides a modified vinyl alcohol polymer having a side chain with an ethylenic double bond, and having reduced a water-insoluble content and superior storage stability in the form of an aqueous solution. The present invention also provides a method for producing such a modified vinyl alcohol polymer. A dispersion stabilizer for suspension polymerization comprising the modified vinyl alcohol polymer is also provided that provides superior polymerization stability during suspension polymerization of a vinyl compound, and with which reduced formation of coarse particles, high bulk specific gravity, and superior plasticizer absorbability can be achieved, in addition to reducing fisheyes. The present invention also provides a method for producing a vinyl polymer. The present invention relates to a modified vinyl alcohol polymer (A) having a degree of saponification of 68 mol% or more and less than 99.9 mol%, and a viscosity-average degree of polymerization of 200 or more and less than 3,000, and comprising a side chain with 0.01 mol% or more and less than 0.50 mol% of a double bond derived from an esterification agent, the esterification agent being one or more selected from the group consisting of (i) itaconic acid and/or derivatives thereof, and (ii) methacrylic acid and/or derivatives thereof, and the modified vinyl alcohol polymer (A) having a peak width W 0.05h of at least 2.85 minutes and less than 3.70 minutes at a height of 5% from the baseline in a peak measured by HPLC.

摘要： 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.

摘要： An object of the present invention is to provide a technology of dispersing cellulose readily in a hydrophobic substance such as a resin by treating cellulose being a hydrophilic substance in a system that contains water as a main medium with a polymer dispersant, which has been developed for dispersing a fine and hydrophobic substance such as a pigment, in a simple and efficient manner without conducting surface modification of nanocellulose or other treatments. The object is solved by a process for producing a readily dispersible cellulose composition, the process including dissolving a polymer dispersant having a block copolymer structure having a resin-affinitive segment A and a cellulose-adsorptive segment B in a hydrophilic organic solvent solution, adding a surface active agent to the resultant solution, thereafter adding water to the resultant mixture to prepare an aqueous dispersion treatment agent containing the polymer dispersant, and adding the obtained aqueous dispersion treatment agent to cellulose in a water-containing state or in a dry state, thereby obtaining a readily dispersible cellulose composition. The object is also solved by a process for producing an aqueous dispersion treatment agent for use in the process for producing a readily dispersible cellulose composition, the readily dispersible cellulose composition, and a cellulose-dispersed resin composition using the readily dispersible cellulose composition.
