发明名称 STYRENIC POLYMER
摘要 PROBLEM TO BE SOLVED: To provide a novel styrenic polymer, and a flocculant preferable for treatment of an emulsion type water-soluble cutting oil using it. SOLUTION: The styrenic polymer is represented by formula (1) (wherein m and n represent a number of 1 or more, m:n=3:1-1:2, and they represent the number that the viscosity becomes the range of 0.3-0.5 (using dimethyl sulfoxide as solvent at 25°C)). The styrenic polymer is suitable as a flocculant for treatment of the emulsion type water-soluble cutting oil. COPYRIGHT: (C)2011,JPO&INPIT
