Characterization of ageing of NC based gun propellants by molar mass degradation of nitrocellulose and its modeling by random chain scission models

(Манфред А. Бон. Деградация молекулярной массы нитроцеллюлозы при старении нитроцеллюлозных порохов. Оценка на основе моделей случайных разрыва цепи).Presentation on the National Defense Industrial Association (NDIA) Insensitive Munitions and Energetic Materials Technology Symposium.Document in pdf-format. 2012. – 38 p.An example is presented of the ageing of a gun propellants (GP) followed by molar mass decrease of the nitrocellulose (NC).Сontents:
