Thc differcnccs in performance between PVC materials produced by calcium carbide method and ethylene method wcrc studied, and the molecular weight and molecular weight distribution, rhcological bchaviour and mechanical properties of the two kinds of PVC materials were compared. Based on the cxperimental PVC resin samples, it is found that：1 compared with ethylene mcthod PVC resins, calcium carbide mcthod PVC resins have lower molecular weight and wide molecular weight distribution;2 the plasticizing properties of calcium carbide method PVC dry blends are bcttcr than that of cthylcne method PVC dry blends;3 there are few diffcrenccs hctwcen the mcchanical propcrtics of PVC reins produced by calcium carbide method and ethylene method.
