Abstract
L'invention concerne un complexe d'un polyméthacrylate ou d'un polyméthacrylamide et d'un poly(alcène-1) liquide. Plus particulièrement l'invention concerne un complexe constitué d'un poly(alcène-1) liquide ayant un poids moléculaire compris entre 200 et 10 000 et d'un polymère de 1. un méthacrylate de dialkylaminoalkyle ou un dialkylaminoakylméthacrylamide, 2. un méthacrylate d'alkyle en C1-6 , 3. un méthacrylate d'alkyle en C10 -C14 et 4. un méthacrylate d'alkyle en C16 -C20, ce polymère ayant un poids moléculaire compris entre 5 x 10**4 et 10**6, le rapport pondéral du polymère au poly(alcène-1) étant compris entre 4/1 et 2/3. Les complexes de l'invention conviennent particulièrement bien comme additifs des huiles lubrifiantes.
