Abstract

PURPOSE: To obtain fine polymer particles with a diameter which is uniform and small to such an extent which usual suspension polymerization can not attain, by suspension-polymerizing methyl methacrylate in an aqueous medium containing PVA, an anionic surfactant and a water-soluble electrolyte.
CONSTITUTION: Fine polymer particles, diameter 10W150μ, average diameter 40W 100μ, are obtained by suspension-polymerizing a monomer mixture consisting of 100W80wt% methyl methacrylate and 0W20wt% C1W8 alkyl acrylate in an aqueous medium consisting of 100pts.wt. water, 0.01W0.3pt.wt. PVA, polymerization degree 1,000W3,000, saponification degree ≥80%, 0.001W0.1pt.wt. anionic surfactant and 0.1W2.0pts.wt. water-soluble electrolyte, e.g., NaCl.
EFFECT: After-treatment, which is necessary in usual emulsion polymerization processes, is not required.
USE: The fine polymer particles thus produced are useful in the production of filters, syrups for casting, surface coating agents, etc.
