Notes:
Effects of group IIB metal oxides (viz., ZnO, CdO, and HgO) on ethylene thiourea (ETU) accelerated the curing of acrylic rubber (ACM) have been evaluated with a view to elucidate the cross-linking mechanism with special reference to the role of metal oxides. Best results are obtained with CdO in the presence of ETU. ZnO—CdO or CdO—HgO blends provide no synergism in the state and rate of cure. Formation of metal sulfide and chloride during the cross-linking reaction has been confirmed by XRD and XPS. Examination of FTIR spectra reveals that cross-linking occurs at the C—Cl cure site of the acrylic polymer. Based on spectral and chemical analysis, a reaction mechanism has been put forward. © 1994 John Wiley & Sons, Inc.
