PURPOSE: To form emulsion without unity of liq. drop and phase separation over a long time with the addition of a small amt. of a emulsifier, by prepg. a high polymer emulsifier with polymer having three kinds of constituent unit of specified formula. n CONSTITUTION: The high polymer emulsifier is prepd. with the polymer (C) contg. the constituent unit (A) of formula I (where, R 1 is hydrogen atom. or methyl group, R 2 is hydrogen atom., methyl group, etc., and R 3 is hydrogen atom., methyl group, etc.) and the constituent unit (B) selected from constituent unit (b-1) of formula II (where, R 10 is hydrogen atom. or methyl group, R 11 is hydrogen atom., methyl group, etc., R 12 is hydrogen atom., methyl group, etc., and R 13 is 4W30C alkyl group, etc.) and constituent unit (b-2) of formula III (where, R 16 is hydrogen atom. or methyl group, R 17 is hydrogen atom., methyl group, etc., and R 18 is hydrogen atom., methyl group, etc.), as main constituent unit. n COPYRIGHT: (C)1989,JPO&Japio |
