PURPOSE:To provide a vinyl chloride resin for paste, having high bulk specific gravity, excellent fluidity, a small amount of fine powder produced, ready handleability and not deteriorating operation environment. CONSTITUTION:In producing a vinyl chloride resin for paste by subjecting a monomer consisting essentially of vinyl chloride to emulsion polymerization or micro suspension polymerization to give an aqueous dispersion of vinyl chloride-based polymer and spray-drying the dispersion, 0.2-15 pts.wt. plasticizer based on 100 pts.wt. of the polymer is added to the aqueous dispersion. |
