However, on a kinetic ground, the condensation reactions leading to polyester regradation are expected to be considerably slower because the probability that the free end groups react with a terminal rather than with an inner ester bond of the polyester is very small: an effect of this type might probably be expected to occur only with the monomers whose vapor pressure is particularly high.
