Abstract
PURPOSE: To prepare polymer particles having narrow viscosity distribution and extrudable without variation of the rate of extrusion, by the bulk polymerization of styrene, etc. to a specific viscosity, followed by the suspension polymerization in water.
CONSTITUTION: (A) Styrene or a mixture of styrene and other polymerizable ethylenically unsaturated monomer (e.g. α-methylstyrene) is bulk-polymerized in the presence of (B) a polymerization initiator until the viscosity of the reaction system at 20°C reaches to 100W10,000 (pref. 200W5,000) cps. The solution of bulk (co)polymer is introduced into water containing (C) a suspension stabilizer (pref. a combination of tribasic calcium phosphate and dodecylbenzenesulfonic acid sodium salt), and subjected to the suspension polymerization.
