Abstract
A simple, convenient and reliable calorimetric efficiency scale is pro posed for the evaluation of nucleating additives for polymers. The sca le is based on conventional differential scanning calorimetry cooling runs and makes use of a crystallization range determined in self-nucle ation experiments. It can be correlated with spherulite sizes, and ind icates the potential range of improvement of nucleating additives. Typ ical nucleating agents for isotactic polypropylene are evaluated; at b est they rate at 60 to ca. 70% on this efficiency scale. (C) 1993 John Wiley & Sons, Inc.
