Haloaldebyde Polymers. I. Chain Termination in Anionic Chloral Polymerization

P. Kubisa1) and O. Vogl1)
1) Polymer Science and Engineering, University of Massachusetts

ABSTRACT:  Anionic chloral polymerization can be carried out under certain circumstances in the presence of acylating agents, such as acetyl chloride and benzoyl chloride. Parts of these polymers exhibit a much improved thermal stability. Introduction of acyl end groups into the polymer permits an estimation of the molecular weight of the polymer. DTG was found to be an excellent technique with which to follow the extent of reaction, to assist in the examination of this kind of end group and to follow the thermal stability of chloral polymers.
