Dispersion stabilizer for suspension polymerization |
| abstract |
The present invention provides a dispersion stabilizer having an excellent polymerization stability. When used for suspension polymerization of vinyl compounds even in small amounts, the dispersion stabilizer according to the present invention attains the effects that: with respect to vinyl polymer particles to be obtained, the plasticizer absorptivity is high, leading to easy processing; residualmonomer components such as a vinyl compound can be removed easily; the number of coarse particles is small; the obtained particles are as uniform as possible in particle size so that formation of fish-eyes can be prevented. The present invention provides a dispersion stabilizer for suspension polymerization including a polyvinyl alcohol polymer (A) having a saponification degree of 60 mol% or more and a polymerization degree of 200 or more, and a polyvinyl alcohol polymer (C) obtained by esterifying a polyvinyl alcohol polymer (B) having a saponification degree of less than 60 mol% with a carboxylic acid compound. |
