ãStar polymerization of norbornene derivatives using a tri-functionalized Blechert’s olefin metathesis catalystã?was written by Zhou, Chulu; Hou, Cuiping; Cheng, Jianhua. Recommanded Product: 89466-08-0 And the article was included in Polymer Chemistry in 2020. The article conveys some information:
Blechert’s catalyst (III), one of the powerful olefin metathesis catalysts in ring closing metathesis (RCM), was demonstrated to show living ROMP characteristics towards conventional norbornene derivatives The obtained homopolymers and block copolymers have very narrow D and controlled mol. weights The tri-functionalized ROMP initiator (IV) based on Blechert’s catalyst was isolated in good yield, and showed highly efficient activity in the star polymerization of norbornene derivatives, including bulky fourth generation dendrons, to afford tri-arm star polymers with a precise mol. weight and narrow D. The difference in the solution properties between tri-arm star polymers and linear polymers with similar mol. weights was studied by tandem GPC/light scattering. In addition to this study using 2-Hydroxyphenylboronic acid, there are many other studies that have used 2-Hydroxyphenylboronic acid(cas: 89466-08-0Recommanded Product: 89466-08-0) was used in this study.
2-Hydroxyphenylboronic acid(cas: 89466-08-0) belongs to acyl phenylboronic acid. Phenylboronic acid (PBA) has been used to extract β-blockers (a class of aminoalcohol-containing drugs) from aqueous solution, rat, and human plasma. Recommanded Product: 89466-08-0
