聚乙二醇甲醚
Poly(ethylene glycol) methyl ether
average Mn ~2,000, flakes
产品描述
包装
250, 500 g in poly bottle
5 g in glass bottle
General description
It is a Polyethylene glycol (PEG) macromer with a reactive chain end consisting of methyl ether. Etherification of the PEG chain ends can be undertaken in basic conditions by reacting it with alkyl halides. mPEG can undergo cross linking to form hydrogels; polymerization can be initiated by redox reaction or free radical initiator.
