Abstract

PROCEDE D'OBTENTION D'UN POLYMERE DE BONNE FILABILITE A PARTIR DE DECHETS. IL CONSISTE EN CE QUE L'ON COMPRIME LES DECHETS FINEMENT COUPES AU MOYEN D'UNE VIS JUSQU'A UNE MASSE VOLUMIQUE APPARENTE D'AU MOINS 500KGM, QU'ON LES INTRODUIT DANS UNE BOUDINEUSE DEGAZEUSE A DOUBLE VIS ET QUE L'ON SOUMET LE POLYMERE FONDU A UNE OPERATION DE POSTCONDENSATION. LE POLYMERE OBTENU PEUT ETRE UTILISE EN PUR DANS CERTAINS EMPLOIS TEXTILES ET EN MATIERES PLASTIQUES.
