Abstract The rheological properties and compatibility of PC/PS containing SMA are determined and the possibility of the alloy being used as a new disc material is also discussed in this paper. The results showed that the η a of the alloy decreased markedly on increasing the temperature, shear rate and PS content in the alloy. In addition, it was confirmed by DSC that PC was partly compatible with PS. The influence of SMA added into PC/PS on the compatibility was also studied. The results showed that SMA has compatibilization, apparent viscosity η a of the systems could be lowered by the addition of the compatibilizer, and the results of DSC showed that the Tg of the PC phase got closer to the T g of the PS phase, until it has only one T g . Using SEM, the microstructure of the polymer alloy was studied. It indicated compatibilization was better, consistent with the result of DSC. Finally, it is discussed whether the PC/PS alloy systems with the compatibilizer could be used as the substrate material for optical disks. Copyright © 2003 John Wiley & Sons, Ltd.
