제목 Study on Impact Resistance, Wear Resistance and Crystallization Kinetics of Polypropylene Modified by Complex Crosslinkers
초록 As environmental regulations become strict, automobile industry has focused on the light material to reduce carbon dioxide emission. Among these light materials, polypropylene (PP) has received considerable attention in automobile industry because of low cost and good processability. However, the PP has low impact resistance and wear resistance to be used in various automotive parts. To improve the impact resistance and wear resistance, in this study, linear PP was branched and/or crosslinked by the initiator with the crosslinkers of trimethylolpropane trimethacrylate (TMPTMA) and divinylbenzene (DVB) through the twin screw extruder. The modified PP improved the impact resistance and wear resistance than those of linear PP while keeping process flowability. It is considered that the crystallization kinetics of branched and/or crosslinked PP have an influence on the improved properties.
