An increase in molar mass of PET due to post‐polycondensation and/or transesterfication during drawing at a high temperature of 160 to 230°C was found. Moreover, drawing leads to crystallization and large orientation in the amorphous phase, which results in lower molecular mobility and ...
hybrid nucleating agent could effectively reduce PET's degree of viscosity average molar weight loss.And the result indicated that the viscosity average molar weight of PET with hybrid nucleating agent was obviously higher than PET with sodium benzoate,which was close to PET with the addition of ...
