<正>We study the reasons on the degradation of Poly (p-phenylene terephthalamide) (PPTA) through inherent viscosity.Degradation rate of PPTA influenced by these factors such as time,so- lution concentration,CaCl_2,1-Methyl-2-pyrrolidinone (NMP) and H_2O was analyzed.The result

PPTA;;degradation;;inherent viscosity
