    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.
