PRODUCTION AND STORAGE OF PVC TAR

The ductility-tenacity test has been used to investigate methods of production of PVC tar. Recently available grades of polymer produced by emulsion polymerization have been shown to give PVC tars of improved properties. Storage of PVC tars made from either emulsion or suspension polymer is feasible only at low temperatures. PVC tars have been shown to be stable at 90 deg C for up to 14 days whereas at 130 deg C degradation is virtually complete after four days. Ductility-tenacity test results are below the proposed minimum value after 2 days at 130 deg C or 1 day at 140 deg C, and PVC tars manufactured at these temperatures are likely to be seriously degraded before they can be used.(a) /TRRL/
