Free-radical crosslinking copolymerization

Microgel Formation in Solution by Free-Radical Crosslinking Copolymerization... 

Polymeric gels are crosslinked polymers swollen in a liquid. The polymer serves as a matrix to hold the liquid together, while the liquid inside the gel allows free diffusion of some solute molecules. Polymeric gels can be prepared from either monomeric or polymeric precursors dissolved in a solvent. However, the most commonly used method is the free-radical crosslinking copolymerization of a monovinyl monomer with a divinyl monomer (crosslinker) in solution. In the...

Gels are prepared by free-radical bulk copolymerization. The comonomers (n-AMA and DMA at a specified molar ratio) are injected along with the crosslinker (DVB 0.1% w/w) and the initiator [2,2 -azobis(isobutyronitrile) (0.5% w/w)] between two glass plates. The glass is previously silanized by immersion for two days in a solution of dichlorodimethylsilane (2% v/v) in toluene. The plates are separated by Teflon spacers of specified thickness, and the whole assembly is held together by metal damps. Polymerization is accomplished by incubating the assembly in the vertical position under argon at 60 °C for 18 h.
