By employing such a method, 5 series of elastomers, including natural rubbers, elastomeric polyester fibers and ethylene-octene, ethylene-methyl acrylate as well as SIS triblock copolymers, were investigated with the purpose of studying elongation induced phase structure and mobility changes of the samples. For NR samples, it was demonstrated that there exists a small amount of crystals at RT even for unelongated samples. For both NR and the soft segment of PEE, with the increase of elongation ratio, the elongation-induced crystallinity increases almost linearly in a certain region of R, in accord with the increase of the lamellar thickness of the crystals; The behavior of ethylene copolymers, in terms of elongation induced morphorpholgy changes, are quite different from NR and PEE. The crystals are found to be gradually destroyed with the increase of R, with accord with the decrease of the lamellar thickness; The motional behavior of the soft segment of SIS, changes from "liquid" to "solid", in terms of 13C NMR spin-lattice relaxation.For many of the aformented samples, the dependence of 13C spin-lattice relaxtion time T1 on R are different for different groups, indicating that the changes of mobility at MHz frequency region with elongation are different for different groups.
通过对天然橡胶、聚醚酯嵌段共聚物、乙烯-辛烯共聚物、乙烯-丙烯酸甲酯共聚物、SIS等高分子弹性体样品聚集态结构和分子运动的研究,获得了一些新的实验结果,如:给出了确切的实验证据,证明了室温下未拉伸的天然橡胶样品中存在着微量的结晶;发现随着拉伸比增加,天然橡胶及聚醚酯样品的软段部分会出现拉伸诱导的结晶,且结晶度在一定范围内呈现近似线性的增加,所形成晶片的厚度也随之逐渐增加;而乙烯共聚物随着拉伸比的增加,原有的结晶会被逐渐破坏,晶片厚度逐渐变薄,结晶中的缺陷逐渐增加;随着拉伸比的增加,SIS中PI软段部分的核磁共振弛豫行为会出现从液态到固态的转变等;在对上述多个体系的研究中,还发现不同基团的自旋-晶格弛豫时间随着拉伸比呈现不同的变化趋势,表明不同基团的高频运动随拉伸比增加有不同的变化规律。
