Abstract
PURPOSE: To produce a foamed plastic component having undercuts, by forming a component from foamable plastic particles, which has been prepared by incorporating a crosslinker of a specified radically polymerizable material and by copolymerization, and by coating the surface of the component with a specified solvent.
CONSTITUTION: A radically polymerizable monomer, such as styrene, α-methylstyrene, acrylonitrile or the like is copolymerized with an added crosslinking agent of a radically polymerizable material prepared by suspension polymerization and having two or more vinyl groups, so that the foamable plastic particles are obtained. The particles are prefoamed, then are aged for a certain period of time, thereafter are molded into a foamed plastic component, and the surface of it is applied with a solvent, such as toluene, methylene chloride or the like, by spraying to produce the foamed plastic component having undercuts.
