| 摘要: |
| 提出了一种测定复合固体推进剂粘合剂官能度的新方法.该方法是根据French的聚合物网络结构理论.在羟基粘合剂和二异氰酸酯反应中对不同的当量比测定了交联度,然后把交联度外推到0得到临界交联点r_c.最后由r_c计算出交联官能度.同时给出了用别的方法测定结果的比较资料. |

| Abstract: |
| A new method for fanctionality measurement of hydroxyl terminated binder in composite solid propellnt is presented.The method is based on a network theory of polymer proposed by French,with varying in equivalent ratio, the crossling density is determinedBy reaction of hydroxyl binder with diisocyanate.Then,a critical crosslink point rc can be obtained by extrapolating crosslink density to zero.Finally, functionality is caclulated from rc.The data from other measuring method are also given for comparison. |
