摘要： A process for producing a vinyl chloride polymer which comprises suspension-polymerizing a vinyl chloride monomer or a mixture of a vinyl chloride monomer and a monomer copolymerizable therewith in a polymerization vessel equipped with a reflux condenser, wherein (A) during a certain time in the period from initiation of heat removal by the reflux condenser to termination of the polymerization, a highly active oil-soluble polymerization initiator having a 10-hour half-life temperature of 40°C or lower as measured in benzene in a concentration of 0.1 mol/L is added to the reaction mixture and (B) at least throughout the period from initiation of the addition of the highly active oil-soluble polymerization initiator to termination thereof, an antioxidant is continuously or intermittently added to the reaction mixture. Thus, a process for producing a vinyl chloride polymer through aqueous-suspension polymerization in a polymerization vessel equipped with a reflux condenser can be improved. The ability to remove heat can be efficiently utilized to attain a reduction in polymerization time. In addition, a vinyl chloride polymer of satisfactory quality extremely reduced in fish eyes can be produced.

摘要： A process is provided for producing a vinyl chloride-based polymer by polymerization of vinyl chloride or a monomer mixture containing it in a reaction vessel. Heat generated during polymerization is removed using a reflux condenser. When the polymerization rate is within a range from 30% to 50%, a copolymeric polyether, with a weight average molecular weight of 1,500,000 to 2,000,000, and an ethylene oxide to propylene oxide molar ratio within a range from 78/22 to 82/18, is added to the reaction mass. Foaming of the polymer slurry due to the use of the reflux condenser beyond the point where the polymerization rate reaches 60% is suppressed, and the polymer can be produced with no deleterious effects on the quality of the product polymer.

摘要： The present invention concerns a procedure for the production of PVC particles with a narrow size distribution in the range 10-50 νm, preferably 10-30 νm, in which, in a first stage, a vinyl monomer or a mixture of monomers is polymerised to form a polymer/oligomer seed particle in the range 1-10 νm. In a second stage, another vinyl monomer or mixture of monomers is swelled into the polymer/oligomer seed particles and polymerisation takes place in such a way that they grow into polymer particles of the desired size. It is preferable to use aromatic vinyl monomers or acrylates as the monomer in the seed particles. The seed particles in the first stage can be produced in a two-stage swelling process or by dispersion polymerisation.

摘要： The present invention is directed to a shaped plastic roof tile preferably one shaped like a slate tile. The tile is constructed of the combination of a thermoplastic, preferably one or more polyolefin polymers, and a chlorine containing polymer in an amount to provide a final chlorine content to the tile of between 1% and 65% by weight. The polyolefin polymer is preferably a combination of polyethylene and polypropylene derived from recycled material. The chlorine containing polymer is one or more polymers selected from the group consisting of polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), polyvinylidene dichloride (PVDC), chlorinated polyolefin, acrylate modified PVC, neoprene rubber, copolymers of vinyl chloride with ethylene, propylene, vinyl acetate, vinyl dichloride, and butadiene, copolymers of vinylidene chloride with butyl acrylate and nitrile, and polymer blends of PVC with acrylonitrile-butadiene-styrene (ABS), acrylic-styrene-acrylonitrile (ASA), nitrile rubber, and polyvinyl acetate (EVA). Preferably, the chlorine containing polymer is recycled neoprene rubber.

Further, the invention discloses a process for suspension polymerization of a vinyl compound using the dispersion stabilizer for suspension polymerization.
The dispersion stabilizer for suspension polymerization of the vinyl compound in the invention, by the use of a small amount, exhibits quite an excellent suspension polymerization stability. Further, the suspension polymerization of a vinyl compound using this dispersion stabilizer can produce porous vinyl polymer granules having a sharp particle size distribution and a high bulk density. In the polymer granules, a rate of plasticizer absorption is high to give a high processability, a monomer remaining in polymer granules is easy to remove, and fish eyes in a molded product are decreased in the molding.
