Abstract
PURPOSE: Formable polystyrene resin particles having improved bonding preventing effect, prepared by treating the surface of the particles with an ester of a terrahydric alcoholic ester of a higher fatty acid, containing a tetraester essentially, and having a hydroxyl number of a specific value or below.
CONSTITUTION: The surface of foamable polystyrene resin particles containing a volatile blowing agent, a solvent, etc. are treated with a mixture consisting of (A) a tetrahydric alcoholic ester of a higher fatty acid, e.g. sorbitan stearate, preferably 12W22C fatty acid, containing a tetraester essentially, and having a hydroxyl number ≤50, and preferably (B) a metallic soap or fatty acid bisamide and coated with preferably 0.003W0.3wt% component (A). The resultant coated particles are then previously foamed in a continuous blowing machine, and the foamed particles are matured to give a molded article.
EFFECT: Bonding preventing effect in the previous foaming step and fusion promoting effect in molding.
