| Abstract: | According to a new cluster theory for the concentration-dependence of polymer solution viscosity proposed recently, the concept `ideal polymer mixture' was re-investigated and defined as one in which there does not exist any net attractive interaction between unlike polymers which could result in inter-chain association between unlike polymers.Based on the new definition, a new viscometric criterion for polymer-polymer miscibility was suggested.Namely, if the overall apparent association constant obtained experimentally ( exp ) of a mixture solution deviates positively from the weight-averaged value of the two components' apparent association constants, the mixture could be judged as miscible.It was found that the new criterion agrees well with experimental data. |
