| Abstract: | RuO4 can stain both saturated and unsaturated polymer systems that contain in their unit structure ether, alcohol, aromatic, or amide moieties. Blends of poly(ethylene terephthalate and poly (bisphenol-A carbonate) were prepared from two different solvents; a mixed solvent of tetra-ehloroethane and phenol (TCE/Ph) in a 50/50 ration by weight, and a mixed solvent of o-chlorophe-nol and chloroform. The morphologies of blends were characterized by TEM. In the absence of trans-esterification, blends were found to be partially miscible. Blends containing greater than 70% PC have a compatibility greater in the PET-rich composition than in the PC-rich composition. The observations revealed that the phase strucure of this system is highly sensitive to the molecular weight of PC, the composition of the blends and solvent of the blends. |
