The present application relates to a polypropylene with high melt flow index and a method for producing the same, and meltblown fiber fabrics. A reacting mixture is firstly provided, and a polymerization process is performed to the reacting mixture in a slurry reaction system to obtain the polypropylene. The reacting mixture includes propylene monomers, Ziegler-Natta catalysts, organoaluminum compounds and electron donor. The polypropylene has high melt flow index and adjustable melting point and molecular weight distribution, such that it is used to produce the meltblown fiber fabrics.

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.

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.
