摘要:
A dispersion stabilizer in the present invention contains an aqueous emulsion (a) obtained by dispersing a polymer (A) having an ethylenically unsaturated monomer unit in an aqueous medium, a PVA (B) having a degree of saponification of 65 mol% or more and less than 82 mol% and a viscosity-average degree of polymerization of 250 or more and less than 1500, and a PVA (C) having a degree of saponification of 82 mol% or more and less than 98 mol% and a viscosity-average degree of polymerization of 1500 or more and less than 4000. The dispersion stabilizer contains: 7 to 51 mass% of the polymer (A); 40 to 84 mass% of the PVA (B); and 9 to 53 mass% of the PVA (C), with respect to a total amount of the polymer (A), the PVA (B), and the PVA (C). A vinyl resin satisfying required performance can be obtained using the dispersion stabilizer.
摘要(中):
本发明的分散稳定剂含有通过将具有烯键式不饱和单体单元的聚合物(A)分散在水性介质中而得到的水性乳液(a),皂化度为65摩尔%以上的PVA(B)和 粘度平均聚合度为250以上且小于1500的PVA(C)和皂化度为82摩尔%以上且小于98摩尔%的PVA(C),粘度平均值 聚合度为1500以上且小于4000.分散稳定剂含有:7〜51质量%的聚合物(A); 40〜84质量%的PVA(B); 相对于聚合物(A),PVA(B)和PVA(C)的总量,为9〜53质量%的PVA(C)。 使用分散稳定剂可以得到满足所需性能的乙烯基树脂。
