Abstract

The accerelating againg tests of various types of nitrocelulose which had deffrent nitrogen content and degree of polimerization were carried out at low tempertures slightly higher than the room temperarure. After aging, Abel test, thermal analysis, ignition temperature test and determination of acid, nitrogen and peroxide content were carried out in order to clarify aging behavior of nitrtcellulose at low temperature. The results obtained are as follows.
There is no difference in thermal analysis and ignition temperature of nitrocellulose before and after aging. But, aging behvior was different with nitrogen content, degree of polimerization and temperature. Moreover, aging caused to decrease a stability nitrocellulose obtained from Abel test and the activation energy of decomposition. Amounts of acid, nitrate ion and peroxide were gradually increased and nitrogen content was gradually decreased at the beginning of aging. On the other hand, amount of peroxide increased after definite induction period.
