Abstract
N-Acryloyl,N'-cyanoacetohydrazide (ACAH) and its complexes with some m etal ions have been investigated as thermal stabilizers for rigid poly (vinyl chloride) (PVC). Their stabilizing efficiencies have been measu red by the continuous potentiometric determination of the evolved hydr ogen chloride gas from the degradation process and by the extent of di scoloration of the degraded samples compared with some conventional th ermal stabilizers. The efficiency of blending ACAH with conventional t hermal stabilizers has been investigated. A probable mechanism for the stabilizing action of ACAH is also proposed. (C) 1998 SCI.
