| 摘要 |
The invention relates to a condensation polymer, as well as to a process for preparation said polymers, having at least one dialkylamide endgroup connect ed through the polymer backbone to a unit derived from an alkylamide, the connection comprising at least one ester linkage. The polymer according to t he 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. |
