Abstract

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.
