| titleOfInvention | Process for producing modified polystyrene resin particles, pre-expanded particles, and expanded molded article. |
| abstract | PROBLEM TO BE SOLVED: To provide a method for producing modified polystyrene resin particles capable of obtaining pre-expanded particles having fine bubbles using a recovered modified polystyrene resin foam molded product as a raw material. SOLUTION: The method for producing expandable resin particles of the present invention is obtained by impregnating and polymerizing polyethylene resin particles with a styrene monomer, and comprises 50 to 80% by weight of a polystyrene resin component and a polyethylene resin component. 100 parts by weight of a modified polystyrene resin containing 20 to 50% by weight and a foamed molded product containing 0.05 to 1 part by weight of R 1 —CONH—R 2 —NHCO—R 3 as a foam regulator, The pulverized product is supplied to an extruder, melt-kneaded, extruded and granulated, and the resin particles obtained are supplied into an aqueous medium and heated to a melting start temperature Tm or higher of the above-mentioned cell regulator, and then 20 to 500 ° C./hour. It cools to 1-90 degreeC with the cooling rate of. [Selection figure] None |
