摘要： A dispersion stabilizer for suspension polymerization of vinyl compounds comprising a vinyl alcohol polymer (A) which has a saponification degree of 30 mol% or more and less than 60 mol% and a viscosity-average polymerization degree (P) of more than 200 and less than 600, and has a terminal alkyl group having 6 to 18 carbon atoms, and in which a content of monomer units having an oxyalkylene group is 0.3 mol% or less and the relationship between the viscosity-average polymerization degree (P) and a modification rate (S)(mol%) of the alkyl group satisfies Formula (1). Thus, there can be provided a dispersion stabilizer for suspension polymerization with which, during suspension polymerization of vinyl compounds including vinyl chloride, even when it is used in a small amount, the absorbency of a plasticizer is high, resulting in easy processing and formation of coarse particles is little and the remaining monomer components can be easily removed.

摘要： A vinyl alcohol polymer having a C2-C20 hydroxyalkyl group in the side chain. It has an excellent thermal stability, as the temperature causing a weight loss of 5 % is higher than 300 °C. As compared with conventional water-soluble vinyl alcohol polymers, which cause so much bubbling in a state dissolved in water when they have high surface activity that the industrial use thereof is problematic, the invention polymer, even when water-soluble, causes little bubbling in a state dissolved in water in spite of the high surface activity thereof, thus being highly useful industrially. It is useful as a thermoplastic resin and a dispersion stabilizer, and is applicable to various uses such as surfactant, paper modifier including paper coating agent, paper additive and pigment binder, adhesive for wood, paper, aluminum foil and inorganic material, nonwoven fabric binder, coating material, warp sizing agent, fiber treatment, sizing agent for hydrophobic fibers of, e.g., polyester, film, sheet, bottle and fiber.
