Abstract: Preparation of uniformly colored expandable styrene polymerizate particles (EPS-particles) by polymerization of styrene optionally with 20 wt.% of its weight of comonomers in aqueous suspension in the presence of colored pigment or dye, with addition of a propellant before, during, and after polymerization is new. An Independent claim is included for a styrene soluble expandable styrene polymerizate particles containing 0.1-15 wt.% of colorant, uniformly distributed in the polymerizate.
