Abstract
PURPOSE: To manufacture a granular vinyl chloride resin for paste with a good regeneration and fluidity and less left monomer, by forming a powder-state vinyl chloride for paste into a grain by utilizing a fluidized bed unit under a specific condition.
CONSTITUTION: A powder-state vinyl chloride resin for paste is heated increasing a room temperature up to 70°C, preferably 30 to 70°C, and is transferred to a fluidized bed unit in which a tower speed of the fluidized bed is kept at 0.005 to 0.4m/sec. to be changed into a grain. The obtained particle has a not less than 100μ average diameter and the over 1.25 times hardness specific gravity measured by a JIS-K-67- 21 than that of the powder-state resin before being changed into the grain, and can be obtained a granular vinyl chloride resin for paste having the dispersion property to the plastic substance such that a valve measured by a grind meter in the JIS-K- 5701 of the zol obtained by mixing 100 weight part of the grain and 60 weight part of dioctyl phthalate by utilizing an Ishikawa-type kneading machine No.18 for 30 minutes is 300μ and less than 300μ.
