涤纶[η]的测定计算与校正公式
摘要
<正> 作为高分子工业(包括涤沦工业)
生产工艺条件的主要依据之一
和质量主要指标——特性粘度
常从相对粘度
通过查表迅速得到
但为克服称样量的差异而引起的误差
本文推导了校正公式(按此式校正
原则上可完全消除上述误差)
并根据校正公式
算出合适的称样量范围
在此范围内
可不必校正
而其绝对误差小于0.1。
Abstract
A formula with corrected terms is proposed to eliminate the errors due to the different weights of samples. A suitable range of sample weights is suggested. With the corrected forrmula
the method used for he determination and calculation of the intrinsic viscosity of poly(ethylene terephalate is improved.
