MSE 430 Fall 2015 Problem Set

A polycondensation reaction takes place between 1.2 moles of a dicarboxylic acid, 0.4 moles of glycerol (a triol) and 0.6 moles of ethylene glycol (a diol). Calculate the critical extents of reaction for gelation using the Statistical Theory of Flory and the Carotheres Theory. Comment on the observation that the measured value of the critical extent of reaction is 0.866.
