## Abstract **Summary:** The chainβlength dependence of the FloryβHuggins (FH) interaction parameter is introduced into the FH lattice theory for polydisperse polymerβblend systems. The spinodals are calculated for the model polymer blends with different chain lengths and distributions. It is found
Model interactions have been studied by phosphorescence quenching to obtain a better understanding of the chain length dependence of interpolymeric chain end-chain end reactions such as those involved in the termination step of free radical polymerization. For small molecule-polymer interactions in
The segment-cloud model for polymer moIecuIes has been used, and the second virial coefficient AZ obtained as a function of the interaction parameter = for linear and branched chains having different values of 11. It is observed that the chain length effect, though much smakr than in the perturbatio
