| 제목 | study on properties of ultra-high molecular weight polypropylene and various low molecular weight polypropylene |
| 초록 | Ultra-high molecular weight polypropylene(UHMWPP) showed unique properties, such as high mechanical strength and high thermal stability.However UHMWPP showed very poor processability because of high melt viscosity.To improve processability of UHMWPP, UHMWPP was mixed with various low molecular weight polypropylenes (LMWPP) by a Kneader. Although LMWPPs used in this study have similar number average molecular weights, they have different melt index due to different polydispersity index (PDI) and percents of ethylene.The rheological, thermal and mechanical properties of blends were depended on the type and content of LMWPP. As the content of LMWPP increases, the mechanical properties of the blends tend to increase or decrease, depending on the type of LMWPP. A melt index value of blend increase as the content of LMWPP increases.However, the lower the melt index value of the LMWPP, the lower the melt index value of blend. |
