Latest Patents
Tomoaki Nakagawa holds a patent for a "Process for preparing vinyl chloride paste resin." This process involves homogenizing a vinyl chloride monomer in an aqueous medium with an oil-soluble polymerization initiator to create a first aqueous dispersion. The method includes a micro-suspension polymerization where a second aqueous dispersion containing a vinyl chloride monomer and a surface active agent is added to the reaction system. This addition occurs after the polymerization has started but before the conversion of the initially charged monomer reaches 30%. The process is designed to enhance productivity by maintaining the heat removal efficiency during polymerization, ultimately increasing the polymer yield per unit volume of the reactor.
