【摘要】 本文描述了用解偏振光强度测定聚合物结晶动力学的仪器。该法不仅可用于无取向聚合物薄膜的测定,亦可用于取向纤维、甚至是在线结晶动力学的研究。本文还研究了光强度与纤维结晶、取向之间的关系。更多还原

【Abstract】 An instrument for determining the rate of crystallization of polymer by depolarized light inten sity method is described. this method is not only used in studying on the crystallization of unorien-ted polymer film but also used in that of oriented fiber even used in measuring the rate of crystan Hization on spinning line, the relations of the light intensity to the crystallization and orientation of fiber are reported.更多还原
