## Abstract A study has been carried out on the kinetics of the emulsion polymerization of 2,3‐dimethylbutadiene‐1,3. The kinetic treatment of Smith and Ewart was applied for the direct determination of the absolute propagation rate constant __k~p~__. The following expression was obtained: __k~p~__
2-Furyloxirane (FO) was polymerized by various anionic and coordination initiators both in bulk and solution. The corresponding polyethers had relatively low DPns (up to about 100) and possessed relatively irregular structures arising from propagation reactions involving both Ca and C/3 oxirane ring
A stereospecific synthesis of trans-l-cyanobutadiene is described. This monomer was polymerized by n-butyl lithium in toluene and in tetrahydrofuran to yield sparingly soluble products. In both solvents, the concatenation was predominatly trans-l,4with a little eis-l,4 and 3,4 content. Copolymers w
## Abstract **Summary:** A polyfunctional 1,1‐diphenylethylene (DPE) agent was prepared by ring‐opening metathesis polymerization of a DPE‐functionalized norbornene monomer. Its reaction with __sec__‐butyllithium gave a novel polyfunctional anionic macroinitiator with one 1,1‐diarylalkyllithium ini
