%X In the presence of a Friedal-Crafts catalyst, the benzoylated PPO (APPO) was prepared by the reaction of PPO with benzoyl chloride. By changing the ratio among PPO, catalyst and benzoylating agent, we obtained a series of samples (APPO) with different substitution levels. The misoibility of PS with various substituted PPO were studied by DSC. When the degree of benzoylation is more than 49 mol%, the blends of APPO/PS show two T, in DSC curves. The effect of temperatures on he phase behafior of A49 PPO/PS blend were studies by DSC.The blend system was found to exhibit both UCST and LCST behavior. It is also found that the thermally induced phase separatioh is reversible.
