Abstract[English]
A composition includes a polyfunctional poly(arylene ether) having an end group including a linking group and a terminal functional group, wherein the terminal functional group comprises a hydroxyl group or a salt thereof, and the linking group comprises a substituted or unsubstituted saturated hydrocarbylene group, or a substituted or unsubstituted saturated poly(hydrocarbylene ether) and a polyol. The composition is substantially free of a volatile organic solvent or the composition includes 0-5,000 ppm of a poly(arylene ether) comprising a linking group comprising a carbonate functional group, an ester functional group, or a combination thereof. A method for the manufacture of a polyfunctional poly(arylene ether) is also disclosed.[French]
Une composition comprend un poly(arylène éther) polyfonctionnel avec un groupe terminal comprenant un groupe de liaison et un groupe fonctionnel terminal, le groupe fonctionnel terminal comprenant un groupe hydroxyle ou un sel associé, et le groupe de liaison comprenant un groupe hydrocarbylène saturé substitué ou non substitué, ou un poly(hydrocarbylène éther) saturé substitué ou non substitué et un polyol. La composition est sensiblement exempte d'un solvant organique volatil ou la composition comprend de 0 à 5 000 ppm d'un poly(arylène éther) comprenant un groupe de liaison comprenant un groupe fonctionnel carbonate, un groupe fonctionnel ester, ou une combinaison associée. Est également divulgué un procédé de fabrication d'un poly(arylène éther) polyfonctionnel.
