Modeling and semi‐batch control of cross‐link density distribution in the free‐radical copolymerization of vinyl/divinyl monomers

A general model has been developed to describe the cross‐link density development during the free radical copolymerization of vinyl/divinyl monomers. The conventional copolymerization theory based on the terminal model is applied to the cross‐linking system in a novel way. The cross‐link density profile is illustrated for both batch and standard semi‐batch processes. A new semi‐batch feed procedure is proposed that results in a uniform …
