Abstract

En forbedret fremgangsmåte for fremstilling av ekspanderbare polymerpartikler er tilveiebrakt. Den kontinuerlige fremgangsmåten som er beskrevet fremstiller ekspanderbare polymerpellets i et enkelt trinn av farene iboende i fremgangsmåter ifølge tidligere kjent teknikk benyttet for det samme elimineres. Polymerene som her fremstilles har ensartet størrelse, og kan støpes til forskjellige artikler ved å benytte eksisterende utstyr og teknikker kjent for fagmannen på området.An improved process for the preparation of expandable polymer particles is provided. The continuous process described produces, in a single step, expandable polymer pellets of the dangers inherent in methods of the prior art used for the same are eliminated. The polymers produced here are of uniform size and can be molded to various articles using existing equipment and techniques known to those of skill in the art.
