Title (EN) PROCESS FOR PRODUCING POROUS POLYMER
(FR) PROCEDE DE PRODUCTION D'UN POLYMERE POREUX
Abstract: front page image
(EN)A process for producing a porous polymer from a W/O high-internal-phase emulsion, which comprises the step of polymerizing the emulsion and subjecting the surface of the resultant porous polymer to a physical treatment, e.g., scraping. Thus, the porous polymer can have a reduced difference in structure between a surface part and an inner part thereof. The absorption characteristics of the porous polymer can hence be efficiently improved.
(FR)L'invention concerne un procédé de production d'un polymère poreux à partir d'une émulsion de type huileux à phase interne élevée, consistant à polymériser l'émulsion et à soumettre la surface du polymère poreux obtenu à un traitement physique, par exemple un décapage. Le polymère poreux peut ainsi présenter une faible différence de structure entre une partie de surface et une partie interne. Les caractéristiques d'absorption du polymère poreux peuvent ainsi être efficacement améliorées.
