端羧基 meaning in Chinese
terminal carboxyl group
Examples
- A study on carboxyl terminated unsaturated ployester thickened by diisocyanate compounds
异氰酸酯增稠端羧基不饱和聚酯的研究 - Determination of end carboxyl content in pet chip using photometric method was discussed , the optimiza tion of measuring condition and parameters such as sample weight , concentration of titrant , blank of solvent were stud ied
论述采用光度法测定聚酯切片的端羧基，对称样量、滴定剂的浓度、溶剂的空白等测试条件和参数进行优化选择。 - On the basis of discussing the developmellt of antistatic and amibacterial polyamide generally in past decades , the anistatic and anibacterial methods and technologies of synthetic fibers are suxnmarzed emphasisly in this paper a series of pcaneg block copolymers are synthesized by two steps
采用先合成双端羧基的遥爪预聚己内酰胺，再与聚乙二醇进行酯化、缩聚的方法，合成了pca peg (聚己内酰胺聚乙二醇)嵌段共聚物。 - ( 2 ) the results of impact experiments show that impact strength of pf is improved and improvement lever is related to wpu ; but effect of carboxyl - terminated pu - prepolymer is better , that is to say the interpenetrating networks have priority at toughening of thermosetting resin
（ 2 ）冲击实验结果表明二种pu预聚物均能提高pf的冲击强度，增韧效果与pu质量分数wpu有关；而端羧基pu能使复合物冲击强度达到的最大值比端羟基pu稍大。 - However , due to the poor reactive carboxyl group of c - terminus , it is difficult to derivatize peptides topeptidyl t hiohydantoins for c - terminus , and the schlack - kumpf degradation based on thiohydantoin procedure has not yet been developed to such an efficient method as edman degradation
然而，由于c端羧基的化学性质不活泼，致使schlack - kumpf降解法的研究进展缓慢。但通过近十年的研究表明该方法是很有希望成为常规c端顺序测定的方法。
