Descripción general
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.
Aplicación
Poly(ethylene glycol) methyl ether-attached dendrimers can be used as carriers for anticancer drugs. This novel drug carrier has a biocompatible surface and an interior for the encapsulation of drugs.
It can be used as a pore-forming agent in the preparation of ultrafiltration membranes which are used in the removal of macromolecules.
It can also be used as a starting material in the preparation of a biodegradable amphiphilic copolymer of poly(L-alanine) with mPEG.
