## Abstract Kinetic studies on methyl methacrylate polymerization were carried out with watersoluble 2,2′‐azobisisobutyramidine (ABA). The rate of polymerization was proportional to the square root of the initiator concentration in the solvents chloroform, methanol, and dimethyl sulfoxide (DMSO), w
Al~traet--The kinetics of the termination reaction in the anionic polymerization of methyl methacrylate, using monofunctional initiators with sodium as the counterion in the presence of excess NaB(C6Hs) 4 have been studied. For monitoring the living-end concentration, a labelling technique was used.
On the basis of so-called linear free enthalpy correlations, a method is developed to predict vinyl contents of polybutadienes from anionic polymerizations with butyllithium in nonpolar solvents in the presence of bases. According to Reichardt with an extension by Langhals, a transition energy scale
A transition energy scale was established on the basis of dimethyl indoaniline as organic dye for 23 mono-and bidentate polar additives. From polymerization experiments of isoprene with s-butyllithium in mixtures of n-hexane and the selected bases, the microstructure of polyisoprenes was determined
