摘要： This invention relates to a method for graft-copolymerizing vinyl chloride monomer to a polyfluorine resin to produce resins of improved physical properties and processability parameters. The vinyl chloride monomer and polyfluorine resin are first treated in a highly alkaline medium and at a high temperature, and the mixture is stirred. Suspension agent(s), water and an initiator are added to the mixture after the temperature thereof has been lowered. The resultant mixture which has been stirred and homogenized is heated to a temperature at which polymerization is completed. Thereafter the mixture is neutralized, washed, and dried. A product having improved impact strength and resistance to heat and abrasion results.

摘要： The present invention relates to a polymerization process for polymerizing olefinically unsaturated monomer or monomers, wherein inorganic salts are employed to substitute for the traditional emulsifiers employed in the polymerization recipe. The polymerization of olefinically unsaturated monomer or monomers is conducted in the presence of a water soluble initiator. An electrolytic solution of inorganic salt and a buffer solution are introduced into the polymerization mixture at a particular time during reaction period to adequately adjust pH value of the reaction mixture. Further, it is essential to alter the speed of agitation during polymerization by a two-stage operation. The polymer resins so produced have no emulsifier residue contained within the polymer particles, whereby the properties of plastisols from these resins such as viscosity stability, heat stability and clarity are superior to those of the polymer resins produced by conventional emulsion polymerization process or microsuspension polymerization process. The monomer/water ratio of the polymerization recipe thereof is also improved, whereby productivity per batch or run of polymerization is increased.

摘要翻译： 本发明涉及用于聚合烯属不饱和单体或单体的聚合方法，其中使用无机盐代替在聚合配方中使用的传统乳化剂。 烯属不饱和单体或单体的聚合在水溶性引发剂的存在下进行。 在反应期间的特定时间将无机盐和缓冲溶液的电解液引入聚合混合物中，以充分调节反应混合物的pH值。 此外，必须通过两阶段操作来改变聚合期间的搅拌速度。 如此制造的聚合物树脂在聚合物颗粒内不含有乳化剂残留物，因此这些树脂的增塑溶胶的性质如粘度稳定性，热稳定性和澄清度优于常规乳液聚合方法或微悬浮聚合方法制备的聚合物树脂 。 其聚合配方的单体/水比也得到改善，从而增加了每批次或聚合行程的生产率。

摘要： This invention offers a functional vinyl halide polymer that has excellent processing properties for the end-user processing without any extra processing aid. This functional vinyl halide polymer has good fusion, lubrication and melting strength in processing. The finished products show a good characterization of high transparence, low air-mark and low flow-mark. The functional vinyl halide polymer is produced by a solution, bulk or suspension polymerization. Vinyl halide or a monomer mixture comprising mainly vinyl halide is polymerized in an aqueous medium in the presence of an acrylic copolymer latex/powder to obtain the functional vinyl halide polymer. The functional vinyl halide polymer manufacturing process mainly comprises the copolymerization or graft-polymerization of: (A) 90.0 wt %˜99.9 wt % based on the total composition of the vinyl halide or the monomer mixture, and (B) 10.0 wt %˜0.1 wt % based on the total composition of the alkyl acrylate monomers or the acrylic polymer latex/powder, wherein the former can be added stepwisely or all in one time and the later can be charged continuously into reactor during polymerization or charged into a reactor before polymerization.
