General description

Methoxypolyethylene glycol 350 is a polymer similar in structure and nomenclature to polyethylene glycols.

Application

Methoxypolyethylene glycol 350 has been used in a study to assess the synthesis of a new class of thermosensitive micellar cyclotriphosphazenes. It has also been used in a study to investigate synthesis of a new amphiphilic poly(organophosphazene) by stepwise nucleophilic substitution.
