The melt viscosity (,Ta) is calculated for polydisperse branched polymers by two methods: (1) by extending Graessley's theory of melt flow of polydisperse linear chains to include the effects of branching, and (2) by empirical deduction leading to the relation (~TB;'/('/L)= [(Ss:)w/ (SL2)~,] w2 for
