Über die polymerisation von 1‐chlor‐2,3‐epoxypropan

Abstract

AbstractThe kinetics and the thermodynamic features of the polymerization of 1‐chloro‐1,3‐epoxypropane with the complex \documentclass{article}\pagestyle{empty}\begin{document}${\rm Cl}_{\rm 5} \mathop {{\rm Sb}}\limits^ \ominus \cdots \mathop {\rm S}\limits^ \oplus {\rm O}_2$\end{document} were studied. It was found that the process proceeds with a negative temperature coefficient, Ea=−51,29 kJ/mol ( − 12,25 kcal/mol), ΔHp=−18,8 kJ/mol (−4,5kcal/mol), ΔSp=−74,5 J mol−1 K−1 (−17,8 cal mol−1 K−1), and with the ceiling temperature of 52,6°C. The molecular masses of the polymers were determined and a possible mechanism of the polymerization process was suggested.
