The effect of blending between glycol-modified poly(1,4-cyclohexylene dimethylene terephthalate) (PCTG) and polycarbonate (PC) matrix on mechanical properties, physical properties and chemical resistance were investigated. The PC/PCTG blend is expected for transparence. The blends of PC and PCTG were prepared in different ratios using a twin screw extruder and fabricated into standard specimen using an injection molding technique. A blend formed with those two polymers exhibits good chemical resistance as well as good heat and impact resistance. The blends of PC and PCTG were prepared in different ratios using the twin screw extruder and fabricated into standard specimens using the injection molding. The miscibility of these blends was evaluated by Tg measured from dynamic mechanical thermal analysis (DMA). Single Tg of partially miscible blend was found at PCTG content. Partially miscible blend offered improvement in impact strength and processability compared to those of pure PC.
