Effect of polyradicals on gel formation in free radical polymer modification

The formation of polyradical chains is an important feature in free radical polymer modification with crosslinking. The effect of these polyradicals on the prediction of the gel point is theoretically investigated using the method of moments. The polyradical model derived gives a criterion for gelation, xrW,0 = 1, which fully agrees with the Flory‐Stockmayer classical theory. The validity of the widely used monoradical assumption and the …
