Therefore, if it is necessary to take out the produced graft polymer in solid form, it is necessary to use a precipitation purification method using a poor solvent or to remove the organic solvent using a dryer.

を低下させる為好ましくない。These vinyl monomers or monomer mixtures must be liquid at the polymerization temperature used to produce the graft polymer, at least 90% of which must be insoluble in water, and must be capable of dissolving the macromonomer. If the proportion of components soluble in water is 10% or more, polymerization occurs in water and the purity of the graft polymer decreases, which is not preferable.

とによりグラフトポリマーを製造することができる。The method for producing the graft polymer of the present invention is based on suspension polymerization using water as a medium. A vinyl monomer solution in which a macromonomer and a polymerization initiator are dissolved is initially charged, dividedly, or continuously into a polymerization vessel containing a dispersant, a surfactant, and the reaction solution is subjected to a predetermined reaction. A graft polymer can be produced by polymerizing for several hours at a given temperature and stirring speed.

く、好ましくない。The polymer composition of the macromonomer and vinyl monomer used in the suspension polymerization is 0.5/99.5 to 70/30.
It is preferable that it is, and it is more preferable that it is 5/95-50150. The charging composition of macromonomer is 0.
If it is less than 5%, the grafting effect of the macromonomer will not be sufficiently reflected in the physical properties of the produced graft polymer, which is undesirable. If it is more than 70%, the macromonomer will not dissolve, or even if it is dissolved, the viscosity of the vinyl monomer solution will decrease. This is not preferable because it becomes too high and tends to cause blocking during suspension polymerization.
