FLUORINATED PITCH HAVING SURFACE ACTIVITY POWER AND SURFACE ACTIVATING METHOD OF FLUORINATED PITCH

摘要

PROBLEM TO BE SOLVED: To provide fluorinated pitch dispersible in water without using a surfactant. SOLUTION: This fluorinated pitch having surface activity is obtained by reacting fluorinated pitch with a diamine compound. The diamine compound is expressed by the formula [wherein R is a 1-3C alkyl; (n) is an integer of 2-5] and is e.g. N,N-dimethyl-1,3-propanediamine.
