Method for manufacturing rubber-reinforced styrenic resin powder and rubber-reinforced styrenic resin powder

Abstract

A method for manufacturing a rubber-reinforced styrenic resin powder comprising 40% by mass or more of a rubbery polymer, satisfying the following conditions (1) to (4):(1) at least first and second coagulation baths are provided;(2) the first and second coagulation baths are connected;(3) an emulsified dispersion of fatty acid amide is supplied to the connecting part in an amount of 0.2 parts by mass to 2.0 parts by mass (solid content) with respect to 100 parts by mass (solid content) of a slurry; and(4) a temperature in the second coagulation bath is equal to or higher than a temperature in the first coagulation bath.

         2 . A rubber-reinforced styrenic resin powder comprising 40% by mass or more of a rubbery polymer, and having more than 4.0% by mass of the powder passing through a 200-mesh plain weave wire mesh (according to JIS G3555-2004) made of stainless steel wire with a wire diameter of 0.10 mm, wherein a fatty acid amide is present on 50% or more of the surface of the powder.
