The results showed that PPC was a thermotropic liquid crystal and displayed the cholesteric banded texture. The reaction conditions had the distinct effects on the propoxy content and liquid crystal property of PPC, with the reaction temperature and content of propionyl chloride increased, the degree of substitution of propoxy increased at the beginning, then trended to steady. The transition temperature and range of liquid crystalline phase were changed with the DS of propoxy, as the DS of propoxy increased, the melt point decreased, and the liquid crystalline phase transition temperature range of PPC get wider.

结果表明，产物PPC具有明显的热致液晶性能，且呈现出胆甾型液晶的彩色条纹织构；反应条件对产物丙酰基含量和液晶性能有显著影响，随反应温度提高和丙酰氯用量增加，产物丙酰基的取代度先增大，后趋于稳定；其相转变温度和温域随丙酰基取代度改变而相应变化，随丙酰基的取代度增大，产物的熔点降低，液晶温度范围变宽。

此外，在大量mPE和mPE/LDPE共混合金动态剪切流变试验数据的基础上，拟合并推导出能够同时反映PE和mPE/LDPE共混合金熔体粘度对剪切速率和温度依赖性的本构方程，并且通过分析发现，方程中的α值对PE和mPE/LDPE共混合金的熔体粘度的剪切速率依赖性影响较大，α值越大，其熔体粘度对剪切速率越敏感。

杉木跟桤木混交以后，保留了纯林的大部分属性，各类群在大型土壤动物群落中的地位基本保持不变，双翅目、蜘蛛目、膜翅目仍然是最主要的类群，但这种混交方式改变了一些土壤动物的群落结构参数，多度和丰富度出现上升的趋势，均匀度显著降低。

The molecular motion of amorphous region at high-frequency was found to be hardly affected during the stretching processes. In summary, elongation has created major but different influences on the morphology and molecular motion of the aforementioned four series of polymeric elastomers. For those elastomers like natural rubber and poly , elongation has induced crystallization of the noncrystalline or the soft segments. The crytallinitiy and the crystal thicknesses increase monotonously during the course of the stretching; On the other hand, the stretching processes for those semicrytalline copolymers like EMA and POE are rather complex, including the formation of crystal at relatively low λand the destruction of the crystal at the utmost λ. It revealed that stretching process has resulted in a decreasing of the thicknesses and a shortening of 〓C T〓s for the orthorhombic crystalline components.

拉伸对上述四个弹性体体系的聚集态结构都产生了很大影响，但是影响的程度和内容因体系而不同，对于本身存在着化学交联或者是物理交联的体系而言，拉伸导致了其中本来难以结晶组分的结晶，且结晶度随着拉伸比增加而增加，与此同时，体系结晶的晶片厚度也会逐渐增加；而对于结晶性共聚物体系，如EMA和POE，结晶区本来起到了物理交联的作用，在这种情况下拉伸的影响变得比较复杂，拉伸对于不同晶型的影响有所不同，在拉伸比较低的情况下体系总体的结晶度会有所增加，说明有新的结晶产生，当接近或达到断裂伸长比时，体系的结晶度会突然降低，含量占优的结晶会被拉伸所破坏，含量较低的结晶在整个拉伸过程中受的影响较小。
