CA 2338464

An improved process for manufacture of expandable polymer particles is provided. The continuous process disclosed produces expandable polymer pellets in a single step while eliminating many of the dangers inherent in processes of prior art employed for the same. The polymers produced herein are of uniform size, and may be molded into various articles of manufacture using existing equipment and techniques known to those skilled in the art.

La présente invention concerne un procédé de fabrication de particules de polymère expansible. Ce procédé, continu, permet de produire des granulés de polymère expansible en une seule étape, tout en évitant les dangers inhérents aux précédents procédés de production de ces produits. Les polymères produits à l'aide de cette invention présentent une granulométrie uniforme, et peuvent être moulés afin de produire des articles variés par l'utilisation de dispositifs et de procédés connus.
