| Abstract: | The technical indexes of the high stiffness impact copolymer of propylene QP73N were determined in accordance with characteristics of the polypropylene plant and the resin products performance, involving melt flow rate of 8-12 g/10 min, isotactic index of 97% or higher and 7.0%-9.0% mass fraction of ethylene in the resin product. The processing and applications of QP73N indicated that the resin reaches a balance between its impact property and stiffness and at same time, maintains the advantages of high resistance to warp and obviously shortened forming cycle. |
