关于A_（a_i）－B_（b_j）型缩聚物网络结构的研究　Ⅱ．网络结构参数的计算

THE INVESTIGATION OF NETWORK STRUCTURE OF A_(a_i)-B_(b_j) TYPE POLYCONDEN SATE Ⅱ. THE CALCULATION OF NETWORK STRUCTURE PARAMETERS

利用作者在文［７］中得到的溶胶凝胶分配方程推导了Ａａｉ－Ｂｂｊ型缩聚物有效交联点，有效弹性链和悬吊链及相应平均链长的计算公式．由有效弹性链密度推算的丁羟聚氨酯平衡态弹性模量和实验结果有着相同的变化趋势，但有一系统偏差．初步探讨了损耗模量与悬吊链节分数间的定量关系．

he formulae calculating effective crosslinking chain elements, effective elastic chains, pendant chains and their average polymerization degree have been deduced by use of the sol gel distribution theory obtained by authors in reference[7]. The experimental and theoretical results about the relation between the elastic modulus and the density of effective elastic chains of polyurethane containing HTPB are basically identical, but there exists a systematic error.
