Synopsis

Poly (ester)s are degraded by the attack of classical carbenium ions. In a representative study it is demonstrated that the carbenium ions are by far more reactive to cleave ester linkages than are protons. The change of molecular weight distribution of the poly-(ester) during reaction with carbenium ions is reported In an example on low molecular weight compounds the reaction path has been clarified.
