Title (EN) PROCESS FOR COMPOSITE POLYMER BEADS
(FR) PROCEDE DE FABRICATION DE GRAINS COMPOSITES DE SUBSTANCES POLYMERES
Abstract: front page image
(EN)A process of incorporating non-polymeric particulate matter such as magnetic materials, pigments and minerals, into a cross-linked styrene-base polymeric matrix, which process comprises dispersing the non-polymeric particles with a polymeric dispersant in a medium containing one or more vinyl monomers and a crosslinking agent, and adding a polymerization initiator. Typical polymeric dispersants are copolymers, styrenes and tertiary-nitrogen-containing vinyl monomers. Non-polymeric particulate matter incorporated into polymeric beads by this process is resistant to chemical attack and the beads may be used to prepare composite adsorbents or ion exchange resins.
(FR)Un procede d"incorporation de materiaux particulaires non polymeres tels que des materiaux magnetiques, des pigments et des matieres minerales, dans une matrice polymere a base de styrene reticule, consiste a disperser les particules non polymeres a l"aide d"un dispersant polymere dans un milieu contenant un ou plusieurs monomeres vinyliques et un agent de reticulation, et a ajouter une amorce de polymerisation. Parmi les dispersants polymeres typiques on peut citer les copolymeres, les styreres et les monomeres vinyliques contenant de l"azote tertiaire. Le materiau non polymere en particules incorpore a ces grains de polymeres selon ce procede resiste aux attaques chimiques et les grains peuvent etre utilises pour preparer des absorbants composites ou des resines echangeuses d"ions.
