The reverse phase suspension copolymerization of vinyldimethylazlactone (VDM) and methylenebisacrylamide (MBA) has been studied by isolation and analysis of samples over the course of a typical polymerization. Results indicate that MBA is incorporated rapidly to provide a macroporous skeleton. VDM, initially distributed primarily in the organic continuous phase, becomes grafted onto this skeleton at a slower rate upon diffusion into the aqueous disperse phase. The effects of polymerization time and aqueous/organic phase ratio on the development of surface area and porosity, and on protein immobilization have been studied.
