In this experiment,the dependence of viscosity on shear
rate and the sensitivity of temperature for TPVA melts in
the capillary flow were studied.Moreover,the melt spinning
method was used to test the elongational flow properties of
TPVA.The uniqueness of this method lies in the variety of
the elongation rate in the flow direction (which is an unsteady
elongational flow).The advantage of this method is that the
experimentation and the actual production are quite similar.
The actual production conditions can be closely simulated
and thus,results are more in keeping with information needs
of the manufacturing process.In this study,the shear and
the elongational flow properties of TPVA melts with different
plasticizer contents and degrees of polymerization were
tested and analyzed.Thus,this study offers a better under-standing
of TPVA rheological properties affected by TPVA compositions.

在这个实验中,依赖于shearrate粘度和温度的敏感性TPVA融化在毛细管流动进行了研究.此外,融化spinningmethod被用来测试ofTPVA拉伸流动特性.这种方法的独特性在于品种在伸长速率在流动方向(这是一个unsteadyelongational流).该方法的优点是theexperimentation和实际生产非常相似.实际的生产条件可以密切simulatedand因此,结果更符合信息needsof制造过程.在这项研究中,剪切和拉伸流动特性与differentplasticizer TPVA融化的内容和程度的聚合weretested和分析.因此,这项研究提供了一个更好的under-standingof TPVA流变特性受TPVA成分.
