Patent

CA 2368167

The invention relates to a condensation polymer, as well as to a process for preparation said polymers, having at least one dialkylamide endgroup connected through the polymer backbone to a unit derived from an alkylamide, the connection comprising at least one ester linkage. The polymer according to the invention can be linear or branched. The condensation polymers can be very widely used in technically different fields, both in thermosetting and in thermoplastic applications. The invention also relates to a composition comprising the condensation polymer according to the invention, an active substance and a polymer, as well as to a process for incorporating an active substance in an object comprising at least of a polymer composition, by bringing the object into contact with the active substance. More in particular, the invention relates to the dying of polymer fibres.

Cette invention a trait à un polycondensat ainsi qu'à un procédé de préparation de ce polymère. Ce polycondensat possède au moins un groupe dialkylamide rattaché par le squelette du polymère à un motif dérivé d'un alkylamide, la connexion comportant au moins une liaison ester. Ce polymère peut être linéaire ou ramifié. Il est possible d'utiliser très largement ces polycondensats dans des domaines technologiquement différents, tant en thermodurcissage qu'en thermoplastique. L'invention, qui porte également sur une composition renfermant ce polycondensat, une substance active et un polymère, concerne, en outre, une technique permettant d'incorporer une substance active à un objet composé d'au moins une composition polymère et ce, par entrée en contact de l'objet avec la substance active. Elle traite, plus particulièrement, de la coloration de fibres polymères.
