Abstract

PURPOSE: To obtain the titled polymer useful as expandable polymer beads, etc., having a narrow particle size dstribution, by subjecting a monomer, e.g., styrene, etc. to bulk polymerization to a specific viscosity, feeding the polymer to water, followed by adding a specified amount of a monomer having no polymerization initator, and carrying out suspension polymerization.
CONSTITUTION: First, polymerizable ethylenic unsaturated monomers consisting essentially of styrene is subjected to bulk polymerization in the presence of a polymerization initiator until a viscosity of the reaction system at 20°C becomes 100W 10,000 centipoise to give a bulky styrene (co)polymer, which is fed to water containing a suspension stabilizer. 200W900pts.wt. polymerizable ethylenic unsaturated monomers consisting essentially of styrene containing no polymerization initiator based on 100pts.wt. monomer subjected to bulk polymerization is added to the reaction system and subjected to suspension polymerization. The polymerizationinitiator for suspension polymerization is added to the reaction system before the bulk polymer is fed to the suspension polymerization system.
