The cloudiness method and the intrinsic viscosity method were used for determining the solubility parameter and its three dimensional components. 用浊度法估测该聚合物的溶度参数,并用特性粘度法对其溶度参数分量进行了订定。
Thus, the isoelectric points of creatine under different temperature were obtained. The experimental results show that the higher the temperature of the solution, the lower the isoelectric point, and the larger intrinsic solubility. 结果表明,当体系温度越高时,相应肌酸的等电点越低,本征溶解度越大;
The effect of VTMS on the intrinsic viscosity and solubility of the polymers is discussed. 探讨了VTMS的投料比对聚合物的特性粘度和水溶性的影响;
Intrinsic viscosity was used for determining the solubility parameter, the result was 22.10 ( J/ cm 3) 1/ 2? 用特性黏度法测定了该聚合物的溶解度参数为22.10(J·cm-3)1/2。
We measured the physical and chemical properties of HPC, such as degree of substitution, degree of deacetylation, intrinsic viscosity, viscosity average molecular weight, bulk density, solubility, temperature of glass transition, and characteristics of infrared spectrum. 并且测定了羟丙基壳聚糖的取代度、脱乙酰度、特性粘度、粘均分子量、堆密度、溶解性、玻璃化温度、红外光谱特性等理化性质。
