1.A Method of Controlling the Structre of Active Core During Preparing Star Polymer
一种控制合成星型聚合物的活性核结构的方法收藏指正
2.ATRP of MMA initiated from hyperbranched macroinitiator (HP-Br) in the presence of Cu(I)Br and N,N,N′,N′,N″-pentamethyldiethylenetriamine (PMDETA) resulted in multi-arm star polymers (HP-g-PMMA). Then ATRP of HEMA with HP-g-PMMA as polymeric initiator afforded another multi-arm star polymer with hydroxyl groups (HP-g-PMMA-b-PHEMA).
端羟基超支化聚 (3 乙基 3 羟甲基氧杂环丁烷 )与 2 溴 异丁基酰溴反应制得大分子引发剂 (HP Br) ,以Cu(I)Br和N ,N ,N′ ,N′ ,N″ 五甲基二乙基三胺 (PMDETA)为催化体系 ,进行甲基丙烯酸甲酯 (MMA)的ATRP反应 ,得到以甲基丙烯酸甲酯为臂的多臂星状超支化聚合物 (HP g PMMA) .收藏指正
3.Preliminary Study of Polymer Paraffin Inhibitor with Star Shape Structure
星形结构聚合物防蜡剂的初步研究收藏指正
4.And it was supposed that PS-POSS, PMMA-POSS、 PAS-POSS and PHS-POSS polymers mainly formed star-structured materials, while PVP-POSS polymer mainly possessed net-work structure. 5. The thermal properties of POSS-based hybrids were characterized by DSC aind TGA.
4.通过对~1H-NMR谱的计算,POSS分子中约有5-8双键参与了聚合,并初步认为PS-POSS、PMMA-POSS、PAS-POSS和PHS-POSS系列聚合物主要以星型结构为主,而PVP-POSS聚合物主要以网络结构为主。收藏指正
5.The spray consists of a synthetic polymer mixed with ethanol and placed in a small, high-tech dispenser that could be mistaken for a prop on the set of Star Trek.
这种喷剂是一种掺有乙醇的聚合物，被置于一个不大而精密中分配器中。这个分配器很像电影《星球大战》中道具飞船带喷咀的推进器，用一外加电场对混合溶液充电。收藏指正
