同时，含100%BO的均聚物A薄膜的断裂伸长率（30.04%）要比含100%BI的均聚物E的断裂伸长率（9.61%）高得多，这归因于含BI的均聚E体系中含有大量的氢键相互作用，强的氢键相互作用限制分子链的运动，从而使薄膜不能实现高弹形变而发生脆性断裂导致较小的断裂伸长率。但是，值得注意的是，随着共聚物中BO含量的变化，它们共聚物的断裂伸长率却并不单调地变化，当BO的含量减小为60%时，共聚物达到最大的断裂伸长率（47.49%），这是因为引入少量BI链节能极大地破坏分子链的规整排列与堆砌，增加自由体积，使分子链运动加快，从而提高薄膜的断裂伸长率。而当BO链节含量继续减小时，体系中相对较多含量的BIA将使得氢键对薄膜的断裂伸长率影响占到主导地位，因而薄膜的断裂伸长率下降，直至BI的含量达到100%，其断裂伸长率降到最低（9.61%）。 [ Last edited by zyblhyzyx on 2011-12-15 at 01:24 ] |

At the same time, the elongation at break of homopolymer A film containing 100% BO is 30.04%, which is much higher than that of homopolymer E containing 100% BI with a elongation at break of 9.61%. It is attributed to the great hydrogen bonding interactions within homopolymer E system containing BI, by which the movement of molecular chains is limited, so that the film can not achieve high-elastic deformation and brittle fracture resulting in a small elongation at break. However, it is worthy to note that with the content of BO changes in the copolymer, and its elongation rate won’t changes monotonously. In fact, when the BO's content was reduced to 60%, a maximum breaking elongation rate was achieved at 47.49%. It might be caused by the introduction of a small amount of BI chain which could greatly undermine the regular arrangement and piling up for molecular chains, increase the free volume and speed up the movement of molecular chains, the film elongation at break thereby enhanced. When the BO chain content continues to decrease, relative large content of the BIA in this system will make the effects of hydrogen bonding on the elongation to break of the film to be a dominant position, and thus the elongation at break of the film decreased, and when the content of BI arrived at 100 %, the minimum elongation at break was obtained as 9.61%. 我的个去，很拗口的。不知道翻译咋样了，将就一下。   |
