The depolymerization of low molecular weight poly(chloroacetaldehydes)

Authors


Abstract

Stability of low molecular weight (D.P.< 300) polychloral has been found to be a function of the amine used as the polymerization initiator. The polymer produced with diethylamine unzips much more rapidly than that made with triethylamine. This investigation also showed that ester endcaps provide little protection from amine-induced depolymerization. The amine-initiated copolymer of chloral and dichloroacetaldehyde behaves anomalously in that it is unstable in the presence of normally inert organic solvents. Mechanisms are proposed to account for these observations.
