Summary: | A method for analyzing molecular weight of the poly-p-phenylene terephthalamide (PPTA) utilizing near infrared spectrum is provided for reducing the time required to analyze the molecular weight of PPTA. The method uses PPTA samples to build a spectrum-viscosity fitting curve. The molecular weight of an unknown PPTA is analyzed via a near infrared analysis software and the spectrum-viscosity fitting curve. The method is beneficial in that it has a short process time and high reliability. |
