摘　　要：在对无规共聚聚丙烯(PP-R)管材料R503性能测试和结构表征的基础上,研究了加工温度和螺杆转速对R503管材性能的影响,并对管材的性能进行了测试。结果表明:R503属典型的宽分布无规共聚聚丙烯树脂,挤出温度和螺杆转速对管材的性能影响较小。管材专用料R503可以在较宽的加工条件下制备出性能优良的管材。On the basis of property measuring and structure characterizing of PP-R pipe resin R503, the influences of pipe processing temperature and extruding speed on the performance of R503 pipe were studied, and the performance of the pipe was tested.The results show that R503 is in typically wide distribution. The extrusion temperature and screw speed have little effect on the performance of the pipe. R503 with good performance can be prepared under the wider processing condition.
