| Abstract: | he thermogravimetric analysis (TGA) of polyoxymethylene (POM) homopolymer and copolymer was investigated both in nitrogen and air atmosphere. It is founcthat the thermogravimetric behavior was related to the mainchain structure and degradation types of POM. The kinetic parameters of POM degradation in air was correlated by Coats-Redfern's method in this paper and the thermostability of POM wasdiscussed as well. |
