Abstract
Disclosed herein is a method comprising masticating a molten polymer; where the polymer is semicrystalline polymer prior to melting; where the masticating polymer is conducted at an elevated temperature of Tm−15K to Tm+90K; where Tm is the crystalline melting point of the polymer; masticating the molten polymer while it is cooled from the elevated temperature to a temperature of Ta; where Ta is a temperature that is greater than Tc−10K, where Tc is the crystallization temperature of the polymer; and masticating the polymer at the temperature of Ta for a time period of 0.1 to 50 minutes.
