Abstract

PURPOSE: To obtain the titled paste resin easily having wide particle diameter distribution, capable of providing a low-viscosity plastisol, by feeding vinyl chloride in two stages in the polymerization of vinyl chloride in an aqueous medium in the presence of a suspension stabilizer.
CONSTITUTION: Vinyl chloride monomer is polymerized in 80W200pts.wt. aqueous medium comprising 0.1W5pts.wt. (based on 100pts.wt. monomer) emulsifying agent (e.g., sodium lauryl sulfate, etc.) and 0.01W1pts.wt. polymerization initiator (e.g., t-butyl peroxypivalate, etc.) in the presence of 0.001W0.1pts.wt. suspension stabilizer (e.g., PVA, etc.). In the polymerization, the initial feed amount of vinyl chloride monomer is 40W90wt% based on total feed amount. When the polymerization conversion of vinyl chloride monomer becomes ≥30wt%, the polymerization is carried out at 35W75°C while the remaining amount of the vinyl chloride monomer is being added.
