## Abstract **Summary:** Polycarbonate (PC)/polyethylene (PE) blend was injection molded at different molding temperatures. The morphological observation by scanning electronic microscope (SEM) indicated that the sample molded at 190โยฐC contained only uniformly dispersed spherical PC particles. The
The orientation of polymer chains after injection molding is usually studied using techniques that measure the average orientation of molecular segments. Small-angle neutron scattering (SANS) is a technique for measuring the overall chain orientation and is very sensitive to molecular anisotropy. In
