The synthesis process of ultra-high molecular weight PVC resin was introduced.The ul-tra-high molecular weight PVC resin with an average polymerization degree of 5 000 was researched.The conventional quality performance,particle size,particle morphology,and processing performance were characterized and analyzed.The results showed that ultra-high molecular weight PVC resin had good pore structure and plasticization performance,as well as good mechanical properties such as flexibility and wear resistance,and was suitable for the production of elastic products.
