| description | In an aspect, a method for preparing an amphiphilic oxetane oligomer, comprises reacting a reaction mixture comprising oxetane, an alcohol, and a triflate catalyst comprising a rare earth trifluoromethanesulfonate salt to form the amphiphilic oxetane oligomer; wherein a molar ratio of the oxetane to the alcohol is 50:1 to 1:1 or wherein the amphiphilic oxetane oligomer has the formula R(O-(CH2CH2CH2O)n-H)m, wherein n is an integer of 1 to 50, or 2 to 20; m is 1 to 10, or 1 to 4; and R is a fragment of the alcohol.
Selon un aspect, un procédé de préparation d'un oligomère d'oxétane amphiphile consiste à faire réagir un mélange réactionnel comprenant de l'oxétane, un alcool, et un catalyseur triflate comprenant un sel de trifluorométhanesulfonate de terre rare pour former l'oligomère d'oxétane amphiphile ; un rapport molaire entre l'oxétane et l'alcool étant de 50 : 1 à 1 : 1 ou l'oligomère d'oxétane amphiphile ayant la formule R(O-(CH2CH2CH2O)n-H)m dans laquelle n est un nombre entier de 1 à 50, ou de 2 à 20 ; m est un nombre de 1 à 10, ou de 1 à 4 ; et R est un fragment de l'alcool. |
