| titleOfInvention | A kind of eight arms polyethylene glycol, preparation method, functional derivative and the bio-related substance of modification |
| abstract | The present invention discloses eight arm polyethylene glycol (formula 1) of one kind, preparation method, functional derivative and the bio-related substance of modification.Wherein, containing the residue after eight hydroxyls, two glycan molecule dehydroxylation in octavalence division center CORE, n is the degree of polymerization of polyglycol chain, is selected from 1~2000.The eight arms polyethylene glycol has monodispersity or polydispersity.Initiator molecule is at low cost, and purity is high substantially reduces production cost, and the molecular weight and its distributed controll of polymerizate and functional derivative are more accurate, for the bio-related substance of its modification, is conducive to improve product purity and performance.Eight arm polyethylene glycol and its derivative of the invention can also have natural chiral center. |
