EFFECT OF STRUCTURE PARAMETERS OF POLYESTER ON ITS ALKALI REACTION RATE

The effect of the supermoleclar structure of polyester on the effective alkali hy-drolysisis rate constant k has been investigated in the paper.That the average non-crvstal line volume around per crystal grain has a close relation to the k is proved byexperiments.A simple and effctive method for assessing what effect of the super-molecular structure on the k by its CDT value( Critical Dissolution Time) has beenput forward.
