During the non-isothermal crystallization, compared with common PE, the cooling rate had less impact on the crystallization rate of mPE. Second, the sensitivity of the melt viscosity of mPE to the shear rate was poor, and the introduction of long chain branches onto the molecular structure of mPE could improve the dependence of their melt viscosity on both shear rate and temperature. In the extensional rheometric tests, the occurrence of phenomena of'strain hardening' relied on the structure of linear long chains, and mPE didn't show the behavior of'strain hardening', which implied that the melt strength ofmPE was poor.

其中通过共聚方法在mPE分子中引入非线性长支链结构，对提高mPE熔体粘度对温度的依赖性作用较为明显，而对提高mPE熔体粘度对剪切速率的依赖性以及对提高mPE熔体强度作用较弱；采用共混方法在mPE体系中引入线性长支链结构，则对提高mPE熔体粘度对剪切速率的依赖性以及提高mPE的熔体强度的作用较为明显，而对于提高mPE熔体粘度对温度的依赖性作用相对较弱。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.
