摘要： 以RuO4为双酚A聚碳酸酯/聚对苯二甲酸乙二酯(PC/PET)共混体系的薰染剂,可成功地用透射电镜观察其微观形态和相结构。该体系两相微观结构受原料分子量、组成和溶剂的影响。

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-Acarbonate) 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% PChave 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.
