METHOD FOR PREPARING VINYL CHLORIDE-BASED POLYMER AND VINYL CHLORIDE-BASED POLYMER PREPARED THEREBY - A simplified explanation of the abstract
This abstract first appeared for US patent application 18030953 titled 'METHOD FOR PREPARING VINYL CHLORIDE-BASED POLYMER AND VINYL CHLORIDE-BASED POLYMER PREPARED THEREBY
Simplified Explanation
- The patent application describes a method for preparing a vinyl chloride-based polymer with improved melting rate, mechanical properties, and low harmfulness. - The method involves pre-mixing and injecting a mixed dispersant consisting of high hydration polyvinyl alcohol and a metal carbonate before polymerization. - The vinyl chloride-based monomer is then polymerized using this pre-mixed dispersant. - The resulting vinyl chloride-based polymer exhibits improved melting rate, mechanical properties, and reduced harmfulness compared to conventional methods. - The use of the mixed dispersant comprising polyvinyl alcohol and metal carbonate enhances the overall performance of the polymer.
Original Abstract Submitted
The present invention relates to a method for preparing a vinyl chloride-based polymer showing improved melting rate and mechanical properties and low harmfulness, by pre-mixing and injecting a mixed dispersant comprising polyvinyl alcohol of high hydration and a metal carbonate before performing polymerization, and then, polymerizing a vinyl chloride-based monomer, and a vinyl chloride-based polymer prepared through the method.
