Abstract
PURPOSE: To obtain a copolymer which is a fine uniform particle and excels in fabrication properties and solubility in org. solvents, by a method wherein vinyl chloride is copolymerized with vinyl acetate in an aq. medium contg. a polyoxyethylene-polyoxypropylene block copolymer and a satd. org. acid.
CONSTITUTION: 100pts.wt. of a monomer mixt. consisting of 60W95pts.wt. of vinyl chloride and 40W5pts.wt. of vinyl acetate is copolymerized in an aq. medium contg. (a) 0.05W10pts.wt. of a polyoxyethylene-polyoxypropylene block copolymer and (b) 0.001W0.1pt.wt. of a satd. org. acid having not less than six carbon atoms by using an oil-soluble polymn. initiator. When the amount of te block copolymer is less than 0.05pt.wt., a copolymer having a coarse particle size is produced or blocks are formed. Even when the block copolymer is used in an amount of more than 10pts.wt., an additional effect can not be expected and the cost of production will be increased.
