Beschreibung
Zusammenfassung:	The invention relates to a polymer or oligomer comprising a) An oligomeric or polymeric core comprising carbon atoms and at least one of oxygen atoms and nitrogen atoms, and b) at least three hydrocarbyl terminal and/or pending groups having 12 to 100 carbon atoms, wherein the hydrocarbyl groups are linked to the core via c) a linking moiety comprising i) a urethane group and ii) a group selected from urethane group, urea group, and biuret group. L'invention concerne un polymère ou un oligomère comprenant a) un noyau oligomère ou polymère comprenant des atomes de carbone et au moins l'un d'atomes d'oxygène et d'atomes d'azote, et b) au moins trois groupes terminaux hydrocarbyle et/ou groupes pendants ayant de 12 à 100 atomes de carbone, les groupes hydrocarbyle étant liés au noyau via c) une fraction de liaison comprenant i) un groupe uréthane et ii) un groupe choisi parmi le groupe uréthane, le groupe urée et le groupe biuret.
