| titleOfInvention | Method for producing expandable styrenic polymer particles |
| abstract | (57) [Summary] [Structure] 3-20% by weight based on the styrene-based polymer particles in an aqueous suspension in which the styrene-based polymer particles are suspended. Of the styrene-based monomer is added as an aqueous suspension to be absorbed by the polymer particles, and then substantially all of the polymerization initiator required for the polymerization of the styrene-based monomer is added and absorbed by the polymer particles. The reaction is initiated so that the ratio of the styrene-based monomer added to the total amount of the above-mentioned polymer and the styrene-based monomer added is in the range of 25 to 35% by weight, and then the residual styrene is added. A method for producing expandable styrenic polymer particles, characterized in that a system monomer is supplied and polymerized. [Effect] The coalescence of the polymer particles is prevented, the generation of the fine powdery polymer is suppressed to such an extent that there is no practical problem, and the expandable styrenic polymer particles having a uniform particle size are obtained in a high yield. The productivity can be greatly improved. Further, the expandable styrene-based polymer particles obtained by the present invention are excellent in foam moldability and can provide a foam molded product having good quality and appearance. |
