## Abstract 2,2,6,6βTetramethylpiperidineβ__N__βoxyl (TEMPO)βmediated free radical polymerization of 4βvinylpyridine is found to proceed in a βcontrolledβ manner. A linear increase of molecular weight along with an increase in conversion occurs at varying temperatures. Polymerization of styrene wit
The polymerization of 4-vinylpyridine directly intiated by ceric ammonium nitrate has been investigated. Conversion and ceric ion consumption were studied as a function of reaction variables. Increasing the concentrations of monomer, initiator and ntiric acid each favoured the conversion; it increas
