Title: Coagulant
Inventor: MATSUDA KAORU
IPC: C08K5/098
Filed: 2000-06-01
Abstract: PROBLEM TO BE SOLVED: To produce a coagulant capable of recovering a good quality polymer from a latex by using calcium acetate having an iron content of not more than a specific value of ppm. SOLUTION: A coagulant is produced by using calcium acetate having an iron content of not more than 0.3 ppm. The calcium acetate is available as either an aqueous solution of calcium acetate or a powder thereof. In the case of the aqueous solution, a concentration thereof is preferably not more than 20 wt.% and a pH value is suitably 7 to 8. Allowing a silicon-containing compound to act in reacting slaked lime with acetic acid can stably inhibit the incorporation of iron into the calcium acetate. As a silicon-containing compound, sodium silicate, silicon dioxide and calcium silicate are enumerated and among them sodium silicate is particularly preferable.  Usually, the silicon-containing compound is added in an amount containing 0.05-0.10 wt.% of the Si content based on the amount of slaked lime in the case of sodium silicate or calcium silicate whereas in the case of silicon dioxide it is added in an amount containing 0.5-1.0 wt.% of the Si content based thereon. Quicklime may be used as a substitute for slaked lime. The coagulant is preferably used for an emulsified latex of an acrylic multilayer polymer.
