Reduced viscosity allows also for improved injection moulding. These properties are important especially for high-melting polycondensation polymers. 此外,较低的粘度也可以进一步改善注射成型,尤其对具有高熔点的缩聚物而言,这些性能是非常重要的。
Formula describing the invariable relationship between the reduced viscosity of the polyampholyte at IEP and polymer concentration is obtained. 推导出了等电点下的两性聚合物溶液的比浓粘度与聚合物浓度无关的表达式,并用实验证实了这一关系式。
Prediction and optimal control of reduced viscosity of Polysulfone 聚砜比浓粘度的预报和优化控制
The residual oil reduced viscosity process is an important one of processing heavy oil. 渣油延迟减粘工艺是重要的重油加工工艺,目前很受国内外炼厂重视。
As the radius of the salt anionic ion increased, or as the salt concentration increased, the reduced viscosity and intrinsic viscosity decreased. 非等电区时共聚物在纯水中具有典型的聚电解质黏度特性,随外加盐阴离子半径的增大,或随盐溶液浓度的增大,比浓黏度和特性黏度减小,Huggins常数增大;
