This paper presents a study on distribution phenomena of polymer blends between Polycarbonate Oligomer ( PC Oligomer) and Polycarbonate (PC) with different oligomer contents and fabrication conditions. The samples were prepared in CDform by injection molding and were then cut into 6 pieces with varies distance from its gate. Consequently, each cut samples was sliced with thickness of 100, 400 and 200 m from its surface, respectively. The sliced samples were subjected to differential scanning calorimeter (DSC) analysis to confirm the oligomer contents distribution. It was found that both oligomer constitutions and injection conditions have significant influenced on the phenomena of injection products. The studied results are valuable for application to plastic industries.
