Abstract
Dynamic Mechanical Analysis (DMA) tests are carried out to investigate the viscoelastic deformation of PC, ABS and PC/ABS alloys with ratio of PC to ABS being 80/20, 60/40, 50/50, 40/60, respectively. Storage and loss moduli and loss angle of PC, ABS and PC/ABS alloys are measured from DMA tests from 30 °C in 160 °C at 1 Hz. Glassy temperature of PC/ABS alloys is determined with loss modulus and loss angle curves. Also, static tests are carried out to measure the relaxation moduli of PC, ABS and PC/ABS alloys. Effect of ABS fraction on the glassy transition temperatures and relaxation moduli of PC/ABS alloys is discussed.
