Abstract

L'INVENTION CONCERNE UN PROCEDE POUR INJECTER UN ADDITIF LIQUIDE CONTENANT UN AGENT MODIFICATEUR DE LA MATIERE PLASTIQUE DANS UN COURANT D'UNE MATIERE PLASTIQUE DE BASE. SELON L'INVENTION, ON DIVISE AU MOINS PARTIELLEMENT UN COURANT DE MATIERE PLASTIQUE DE BASE AU MOYEN D'UN DISPOSITIF UTILISE POUR L'INJECTION DE L'AGENT MODIFICATEUR, ON INJECTE L'AGENT MODIFICATEUR DANS LE COURANT PARTIELLEMENT DIVISE DE LA MATIERE PLASTIQUE DE BASE POUR PROVOQUER UN MELANGE INITIAL PAR DISPERSION DE LA MATIERE PLASTIQUE DE BASE ET DE L'AGENT MODIFICATEUR, ET ON SOUMET ENSUITE LA MASSE AINSI MELANGEE A DES ACTIONS DE CISAILLEMENT DANS UN DISPOSITIF D'HOMOGENEISATION POUR DISPERSER DAVANTAGE L'AGENT MODIFICATEUR DANS LA MATIERE PLASTIQUE DE BASE.
