Patent

CA 2277309

The invention relates to a compound of general formula (I) wherein 1< f < 500; 1 < f'15; R and R' .ident. alkyl or aryl and X has formula (II), wherein 2 < n < 140; 1 < (n+n') < 51. The inventive method consists in reacting a polyether-polycaprolactone block copolymer of formula (I) having a molecular weight of 1000-6000, formula (IIa), with a chain developer of formula HO-R'-OH and a diisocyanate of formula HCN-R-NCO.

L'invention concerne un composé présentant la formule générale (I) où 1<f<500; 1<f'15; R et R' alkyle ou aryle et X présente la formule (II). Dans cette dernière, 2<n<140; 1<(n+n')<51. Le procédé consiste à faire réagir un copolymère-bloc de polyéther-polycaprolactone dont le poids moléculaire se situe entre 1000 et 6000 et présentant la formule (IIa) avec un agent de développement de chaîne présentant la formule HO-R'-OH et un diisocyanate présentant la formule OCN-R-NCO.
