摘要：
The morphology of the polycarbonate (PC)/Nylon12 blend was compared with that of PC/Nylon6-12 random copolymer (Nylon6-co-12, 6 content: 64mol%) blend. Specific interaction between PC and Nylon was not detected by FT-IR. DSC and DMA data indicated the presence of double T-g's, corresponding to each component. For the Nylon6-co-12 blend, particles of a minor phase were smaller than those of the other blend. In PC/Nylon6-co-12(50/50) blend, a modulated structure was obtained when melt mixed at 500s(-1). On the other hand, in PC/Nylon12 (50/50) blend, isolated dispersion particles were observed. The formation of modulated structure was interpreted in terms of shear-induced miscibility. PC and Nylon6-co-12 may be miscible under a high shear field in twin-screw kneader, whereas PC and Nylon12 are immiscible under the same processing conditions.
