Abstract

L'invention concerne un procédé de fabrication d'un copolymère multiséquencé, qui est composé d'au moins deux séquences oligoester, oligoéther et/ou oligoétherester différentes, ledit procédé comprenant les étapes consistant à : (a) préparer au moins deux macromonomères α,ω-fonctionnalisés différents du groupe des oligoesters, oligoéthers et/ou oligoétheresters, (b) coupler les macromonomères α,ω-fonctionnalisés par réaction avec un diisocyanate aliphatique en tant que réactif de couplage, de préférence avec HDI, dans un solvant ou un mélange de solvants sans halogène de point d'ébullition élevé et (c) récupérer le copolymère multiséquencé à partir du mélange réactionnel, notamment par un procédé combiné de précipitation-lyophilisation, selon lequel dans une première étape la précipitation du copolymère multiséquencé est réalisée par diminution de la température et dans une seconde étape le solvant ou le mélange de solvant est éliminé.
