New synthesis of amphiphilic copolymers PE-g-PEO via esterfication

A new series of high molecular weight amphiphilic graft copolymers PE-g-PEO has been prepared. The esterifications between PE-p-MS-g-MA and PEO with OH group at the chain end are carried out under different conditions. The compositions of these graft copolymers are studied by NMR and FTIR. It is found to be a convenient and efficient way to prepare high molecular weight PE-g-PEO graft copolymers.
