Abstract
PURPOSE: To obtain the titled solution having a long pot life and good dispersibility of magnetic powder, by adding a vinyl carboxylate and an unsaturated carboxylic acid (anhydride) in portions to the solution polymerization of vinyl chloride with the vinyl carboxylate ester and the unsaturated carboxylic acid (anhydride) in a specific proportion.
CONSTITUTION: A polymerizer is charged with (A) vinyl chloride and (B) a vinyl carboxylate e.g. vinyl acetate, and the resultant mixture is then polymerized in the presence of an ordinary oil-soluble initiator under heating and pressure. (C) An unsaturated carboxylic acid, e.g. maleic acid, and (D) an unsaturated carboxylic acid anhydride, e.g. maleic anhydride, are partially added in the initial stage of the polymerization or before the initiation, and the rest are added up to the conversion of 60% in portions to give the aimed solution. The mixing ratios are as follows: (A):(A+B)=(50W80):100, (D):(C+D)=(60W90):100(wt%), (C+D):(A+B)=(1W5):100(pts.wt.). The average polymerization degree is 100W 400 (preferably 200W400).
