采用温和（5、18和40℃的5.0 l盐酸）和剧烈（沸腾时2.5 N和5.0 N盐酸）两种水解条件，对10个代表性纤维素样品的失重和聚合程度进行了全面研究。样品为纯棉、漂白棉绒、棉绒浆、木浆、纺织人造丝、轮胎纱、Fortisan、G纤维和两种实验人造丝。通过酸水解（基于残留物的重量）测量的结晶度百分比和聚合的稳定度显示取决于是否温和，剧烈或温和加剧烈的条件
A comprehensive study has been made of the effectof time on the weight loss and degree of polymerization of ten representative samples of cellulose using both mild (5.0 l\f hydrochloric acid at 5, 18, and 40 C.) and drastic (2.5 N and 5.0 N hydrochloric acid at boil) conditions of hydrolysis. The samples were purified cotton, bleached cotton linters, cotton linters pulp, wood pulp, textile rayon, tire yarn, Fortisan, Fiber G, and two experimental rayons. The per cent crystallinity as measured by acid hydrolysis (based on weight of residue) and the leveling-off degree of polymerization are shown to be dependent on whether mild, drastic, or mild plus drastic conditions of
