block polymer

基本解釋

A novel block polymer of S-B/I-S is successfully synthesized with ROK as modifier for the first time.
首次以ROK為調(diào)節(jié)劑，采用陰離子活性聚合物方法合成了S-I/B-S新型嵌段聚合物。

Conclusion With PEG- PLGA block polymer as material, the blank nanoparticles could be prepared stably, which would be the foundation for further researches on the drug loaded nanoparticles.
結(jié)論采用PEG-PLGA嵌段共聚物為材料，制備空白納米粒處方工藝穩(wěn)定，可以為進一步制備載中藥有效成分納米粒奠定基礎(chǔ)。
The method requires intrinsic viscosity and size exclusion chromatographic data on the whole sample and that the detector be responsive only to one of the two monomer units of the block polymer.
方法要求測定原試樣的特性粘數(shù)和尺寸排除色譜圖，而檢測器只對嵌段共聚物兩個組份之中的一個有響應(yīng)。首先用均聚物標樣定出尺寸排除色譜柱的響應(yīng)常數(shù)和分子量分離校準曲線。

嵌段聚合物
There was only one peak in the GPC chromatogram. So it indicated that the polymer was block polymer but not blend polymer.
聚合物的GPC譜圖顯示分子量的分布呈單峰分布,說明所得聚合物為嵌段聚合物而非混合物。
