<P>PROBLEM TO BE SOLVED: To provide a method of accurately and rapidly measuring an acid radical distribution in a synthetic resin emulsion such as a synthetic rubber latex, such as of an acrylic emulsion having an acid radical, an acrylic styrene emulsion, a butadiene base, a isoprene base, or a chloroprene base. <P>SOLUTION: In the method of measuring acid radical distribution in the synthetic resin emulsion, a predetermined amount of inorganic base solution of a known concentration is added to the synthetic resin emulsion containing acid radical. The liquid of which pH is adjusted to the alkali side is obtained. Then, potentiometric titration is applied to the liquid using inorganic acid solution, and the acid radical distribution in the synthetic resin containing acid radical is calculated. <P>COPYRIGHT: (C)2007,JPO&INPIT |
