Formation of Porous Polymer Morphology by Microsyneresis During Divinylbenzene Polymerization

Popis výsledku v původním jazyce

This article describes the investigation of the importance of various reaction conditions on microsyneretic pore formation during polymerization of divinylbenzene (DVB) under so-called ?solvothermal conditions. In order to induce microsyneretic pore formation, the most important parameter is an unusually high dilution of monomers with a ?good porogen solvating the polymer chains. High dilution and solvation of the growing poly(DVB) chains promotes the prolongation of the polymer chains rather than theirinterconnection by crosslinking. Consequently, when the polymer gel density reaches the point where syneresis starts, the polymer network is geometrically too extensive to be broken up into precipitating entities and, instead, porogen droplets are formed within the continuous polymer gel. The pore geometry created by microsyneresis offers high surface area in wide mesopores and hence, high capacity for supporting functional groups or reactions with much better accessibility than narrow
