ABSTRACT:
A method for increasing the crystallization rate of a polyethylene terepthalate (PET) prepared based on terepthalic acid (TPA) and ethylene glycol monomers, by adding into said TPA-based PET an effective amount of a polyethylene terepthalate prepared based on dimethyl terephthalate (DMT), in an amount sufficient for said thermally formable composition to have an increase in crystallization temperature as required for the final end-use application.
