Abstract

A convincing mechanistic role that lies behind the elevation of thermal indicative parameters when using Zn carbazone as the initiator for the polymerization of methyl methacrylate monomer. The overall results summed up decisively that increasing concentration of the complex had led to an increase in the glass transition temperature, eliminated the scission of the head-to-head linkage, and the unsaturated end chains scissions. Improvements of the PMMA thermal parameters are thought to have arisen due to role played by the Zn carbazone in increasing the polymer stereospecificity. Tensile testing shows that there is a strong relation between the thermal and mechanical properties of PMMA.
