【発明の名称】分岐構造を有する共重合体を分散安定剤として用いた乳化重合法
Document Type and Number:
Japanese Patent JP2543503
Kind Code:
B2
Abstract:
A graft copolymer having dispersion stabilizing effect, which comprises on the carbon backbone thereof a polymer side chain comprising a carbon chain having a molecular weight of 1,000 SIMILAR 100,000, a fluorine atom containing fluorine side chain and a hyhdrophilic side chain containing a hydrophilic group, the total mean molecular weight of said graft copolymer being 5,000 or more. The graft copolymer of this invention can be used as an excellent dispersion stabilizer for emulsion polymerization, whereby in emulsion polymerization it is possible to attain polymer particle dispersion stability to ensure that the polymer particles will not be agglomerated even if they have been grown to larger particles having a diameter of 0.5 mu or more and that dispersion of the polymer particles having a large and uniform particle diameter is obtained.
