inherent viscosity

Moreover, a heat resistant polyester polyols with forseeable molecular weight and inherent viscosity and stable synthesis techniques were prepared through regulating the THEIC/ glycerol, OH/ COOH and triol/ diol mole ratios in original components.

通过调节组分中的THEIC/甘油、羟基/羧基及三元醇/二元醇的摩尔比例，能够稳定合成工艺，制得耐热性能好、具有预定分子量和特性粘数的聚酯多元醇齐聚物。

The results show that the resole resin whose methylol group index is about 3 and inherent viscosity is about 8 satisfies this system.

结果显示适合于这种体系的可熔性酚醛树脂的羟甲基指数为3左右，固有黏度为8左右；

The effects of screw barrel temperature and screw block structure on the extrusion technology, as well as the connection between screw speed and inherent viscosity of PEI were discussed.

讨论了螺杆筒体温度、螺块结构对反应挤出工艺的影响及螺杆转速与PEI特性粘度的关系；

Their inherent viscosity was low and solubility was high, consistent with a highly branched structure.

所有聚合物都具有粘度低、溶解性好的特点，这与它们高度支化的结构有关。

The spinning solution would better with concentration of 14-16%, inherent viscosity of polymer of 1.5-1.8 and processing temperature of 50-70 ℃.

较适宜的纺丝原液的浓度在14-16%，聚合物的比浓对数粘度为1.5-1.8，加工温度为50-70℃。
