摘要
Abstract
The rheological properties and pressure-volume-temperature (PVT) relationships of polypropylene(PP) were studied using seven-parameter-Cross-WLF viscosity model and modified two-domain Tait state equation. Under defined molding conditions, the whole injection molding process could be described. The theoretical volumetric shrinkage of PP was calculated to be 5.58%, which was approximate to the practical measured value of 5.46 %.关键词
