It was learned from Liaoyang Petrochemical Company that this company's “preparation method for the preparation of polypropylene with high chlorinated chlorinated polypropylene†obtained the invention patent authorization of the State Intellectual Property Office. At present, the isotacticity and crystallinity of polypropylene prepared by slurry method at home and abroad are relatively high, and the distribution of particles is not uniform and can not meet certain specific requirements. Since 2004, Liaoyang Petrochemical Organization has specialized in scientific research and successfully developed a new type of polypropylene preparation method. The polypropylene product produced by this method has a relatively high melt index, relatively low isotacticity, crystallinity, and good particle morphology. The degree of chlorination of chlorinated polypropylene produced by this method is greater than 60%. The patented method can realize industrial production in the existing slurry polypropylene plant , and is of great significance for Liaoyang Petrochemical to develop new polypropylene products and enhance market competitiveness.
