Abstract
The rheological properties and crystallization characteristics of low ethylene content poly propylene (EPM) with and without Yittrium oxide (Y2O3) as a filler was investigated by cone-plate viscometer and diffe rential scanning calorimetry. Yittrium oxide had a profound effect on the viscosities of the systems. To determine the nonisothermal crystal lization rate of the materials, a new estimation method was used. From the results, we can conclude that Y2O3 acts as a nucleating agent, wh ich increased the crystallization rate of the EPM. (C) 1996 John Wiley & Sons, Inc.
