| titleOfInvention | A method for manufacturing expandable polystyrene beads by subdividing seed particles |
| abstract | An aspect of the present invention, (a) preparing a emulsion containing styrene-based seed particles, styrene-based monomer, dispersant, initiator and water in the reactor; (b) swelling the styrene-based seed particles by further adding a styrene-based monomer to the emulsion and stirring at a first stirring speed; (c) separating the swollen styrene seed particles by stirring the product of step (b) at a second stirring speed; (d) reacting by further adding a styrene-based monomer to the product of step (c); And (e) obtaining a particle by adding a blowing agent to the product of step (d); wherein the first and second stirring speeds are V 1 and V 2 respectively, and V 1 -V 2 ≥ 20 rpm It provides a method for producing expandable polystyrene particles satisfying the relationship. |
