Abstract

PURPOSE: Titled wet cake which is useful as a polymerization initiator for suspension polymerization and being excellent in storage stability, dispersibility, etc., prepared by mixing water with a finely divided organic azo type polymerization initiator.
CONSTITUTION: An azo compound such as 2,2'-azobisisobutyronitrile, 1,1'-azobis (cyclohexane-1-carbonitrile) or 2,2'-azobis(2,4-dimethyl-valeronitrile) is divided into fine particles at least 95% of which has usually a diameter smaller than about 10μ, by the used of a jet mill, a ball mill, a vibration mill or the like. The resulting fine particles are mixed with water to form cake. The moisture-containing wet cake thus produced is a uniform slightly soft solid containing usually 10W20% of water; completely freed from formation of secondary particles; easy in handling such as storage or transportation; has stable uniformity and when thrown into water and stirred, disperses easily into water to form a dispersion of finely divided particles.
