| titleOfInvention | Multi-arm polyethylene glycol derivative, its intermediate and their manufacture method |
| abstract | There is provided a kind of multi-arm polyethylene glycol derivative with narrow molecular weight distribution.The multi-arm polyethylene glycol derivative that one kind is represented by formula (1).(in formula, L represent with more than 2 carbon atoms and can be in chain with ehter bond straight or branched alkylidene, arlydene or cycloalkylidene, or represent selected from group in the combination of the alkylidene, arlydene and cycloalkylidene；X represents the dehydroxylation residue of the straight chain sugar alcohol with 5 or 7 carbon atoms；M is bonded to the number of the polyglycol chain of X, and the number is 4 or 6；N is the average addition molal quantity of oxyethylene group, and the average mol is 3 to 600 integer；Y represents singly-bound or can be in chain or end has the alkylidene of ester bond, ammonia ester bond, amido link, ehter bond, carbonic acid ester bond, secondary amino group, urea bond, thioether bond or thioester bond；And Z represents chemical reactivity functional group.) |
