摘要
The experimental data obtained from fast heating FTIR spectroscopy have confirmed that a conformational change occurs at about 135 ℃ for semicrystalline iPP. Based on the results of density and WAXD measurements, it can be inferred that the conformational change occurring at 135 ℃ comes from the disordering of helical sequences in non crystalline phase, which is further corroborated by the FTIR study on the chloride polypropylene.
