Title (EN) METHOD FOR PRODUCTION OF POROUS CROSS-LINKED POLYMER MATERIAL
(FR) PROCEDE DE PRODUCTION DE MATERIAU POLYMERE RETICULE POREUX
Abstract: front page image
(EN)This invention is targeted at providing a method for producing a porous cross-linked polymer material excelling in absorption properties and mechanical strength in a short period of time. In the production of a porous cross-linked polymer material from an HIPE, the method of this invention is characterized by comprising a step of polymerizing the HIPE till the bromine value thereof falls to not more than 25% of the value existing prior to the polymerization and a subsequent step of aftercuring the porous cross-linked polymer material by means of an active energy ray or a temperature higher than the polymerization temperature.
(FR)La présente invention concerne un procédé de production rapide de matériau polymère réticulé poreux présentant d'excellentes propriétés d'absorption et de force mécanique. Le procédé de production du matériau polymère réticulé poreux à partir d'une émulsion à phase interne élevée (HIPE) consiste d'abord à polymériser l'émulsion HIPE jusqu'à ce que sa valeur de brome chute à 25 % maximum de la valeur qui existait avant la polymérisation, puis à post-durcir le matériau polymère réticulé poreux par un rayonnement d'énergie active ou par une température supérieure à celle de la polymérisation.
