| 摘 要： | 用ＷＡＸＤ和ＳＡＸＳ研究交联１，４－顺式聚丁二烯的取向结晶．结果表明：该试样在拉伸状态时，形成折叠链片晶，而不是伸直链纤维晶．片晶之间不断产生新的片晶，使长周期减小，并且片晶的横向尺寸不断增大，由此导致结晶度增大．

| 关 键 词： | 顺式聚丁二烯，取向结晶，片晶，拉伸比，长周期 |

| Abstract: | Oriented crystallization of cross linked cis-1,4-polybutadiene was investigated by WAXD and SAXS. The results showed that the samples formed "folded chain'lamellar crystallites rather than "extended chain' crystallites in the stretched state. Because new lamellar crystallites continuosly formed between old ones, the long period decreased and the lateral dimension increased gradually,thus resulting in the increase of crystallinity. |
