Abstract
Blends of poly(2,6-dimethyl-l,4-phenylene ether) (FPO) and a tactic polystyrene (PS) have been prepared by mechanically mixing powders of the two polymers and subjecting the mixtures to three different thermal treatments. Three different
compositions were studied by the dynamic mechaniacl and DSC techniques. The weight fractions of FPO m the mixtures
were 0.25, 0.50 and 0.75. The dynamic mechanical measure
ments indicate that partial mixing took place but that two
distinct phases, one rich in PS and the other in FPO, exis n all the mixtures studied. Each phase exhibits a charactenstlc
relaxation peak associated with the glass transition of that
phase. DSC measurements, on the other ad, reveal on])'. a single glass transition apparently charactensbc of the PS nch
phase in each case. The results indicate that a given type of experiment will indicate compatibility or incompatibility depending upon the size of the molecular process it represents.
