N-Acryloyl,N@-cyanoacetohydrazide (ACAH) and its complexes with some metal ions have been investigated as thermal stabilizers for rigid poly(vinyl chloride) (PVC). Their stabilizing efficiencies have been measured by the continuous potentiometric determination of the evolved hydrogen chloride gas fr
## Abstract Plasticized poly(vinyl chloride) (PVC) was surface modified by nucleophilic substitution of the chlorine atoms of PVC by sulfide ions in aqueous media in the presence of a phaseβtransfer catalyst (PTC) to make it migration resistant. The modified PVC was sterilized by steam autoclaving
