摘　　要：Polystyrene/Poly(ethylene terephthlate) (PET) blends have been prepared by theheterogeneous free-radical polymerization of styrene within supercritical carbon dioxide-swollenPET substrates. Composition of the blends and the average molecular weight of polystyrene inthe blends can be controlled by equilibration time and reaction condition.Polystyrene/Poly(ethylene terephthlate) (PET) blends have been prepared by theheterogeneous free-radical polymerization of styrene within supercritical carbon dioxide-swollenPET substrates.
