A new model for gelation in free radical polymerization based on the pseudo‐kinetic rate constant method is proposed. This model which considers all of the important reactions in free radical polymerization can be used to make calculations of the average properties during network formation. The model is more general than the statistical model based on Flory/Stockmayer treelike concepts and under special limiting conditions reduces to the Flory/Stockmayer model. The present model is easy to use and provides greater insight into the phenomenon of gelation and growth and structure of crosslinked polymers synthesized by free radical polymerization.
