In all cases  the dependency of the formation of beta phase in iPP on molecular weight of iPP at a defined crystallization temperature range was found. The iPP with high molecular weight possessed a wide range of crystallization temperature in inducing rich beta phase. However  poor or even no beta phase was obtained for the samples with low molecular weight in the same range. In addition  an upper critical crystallization temperature of producing dominant beta phase was found at 125 degrees C. Beyond this temperature  a phenomenon of prevailing alpha phase became obvious.
