    • The preparation of vinyl ester homo- or copolymers by emulsion polymerization is described. The process is performed in the presence of a polymerization-retarding component in at least two phases, the concentration of the vinyl ester monomer in the polymerization mixture in the first phase having been depleted by not more than 50% at the end of the first phase compared to the concentration of the vinyl ester monomer in the polymerization mixture at the start of the first phase, and the concentration of the vinyl ester monomer in the polymerization mixture in the second phase being depleted compared to the concentration at the end of the first phase. The retarding component is depleted during the first phase. In the second phase, the heat of reaction is removed by evaporative cooling. In the first phase, the emulsion polymerization is effected at temperatures up to the boiling point of the vinyl ester-water azeotrope, and, in the second phase, at temperatures above the boiling point of the vinyl ester-water azeotrope.The process is notable for a short cycle time and high space-time yields and can be operated safely.
    • 描述了通过乳液聚合制备乙烯基酯均聚物或共聚物。 该方法在至少两相中在聚合阻滞组分存在下进行,第一相中的聚合混合物中的乙烯基酯单体的浓度在第一相结束时已经耗尽不超过50% 与第一阶段开始时聚合混合物中乙烯基酯单体的浓度相比,第二相中聚合混合物中乙烯基酯单体的浓度与第一阶段结束时的浓度相比有所减少 。 延迟成分在第一阶段耗尽。 在第二阶段,通过蒸发冷却除去反应热。 在第一阶段中,在高于乙烯基酯 - 水共沸物的沸点的温度下进行乳液聚合,而在第二相中,在高于乙烯基酯 - 水共沸物沸点的温度下进行。 该过程在短周期时间和高空时产量方面是显着的,并且可以安全地操作。

    • The invention relates to a method for reducing the amount of residual monomers in aqueous polymer dispersions means of chemical post-treatment. Post-treatment in the aqueous polymer dispersion is carried out by adding a redox system which contains a) 0.005-5 wt. % of an oxidation agent which contains an organic peroxide. and b) 0.005-5 wt. % of a reduction agent which contains sulfinic acids or salts thereof. Additionally. the redox system can, optionally, contain catalytic amounts of a polyvalent metallic ion which can be treated in several valent stages. Post-treatment can be carried out at a temperature ranging from 20-100° C. and at a PH-value ranging from 2-9. The invention also relates to the use of the inventive post-treated polymer dispersion for producing adhesives, coarings, powders, constructive chemical products or for refining textiles or paper.
