Patent

CA 2198143

Adducts useful as fuel or lubricating oil additives are disclosed. The adducts comprise the reaction product of at least one quinone compound and an amine-containing polymeric material comprising at least one member selected from the group consisting of: (i) a first amine-containing polymer derived from a hydrocarbon polymer having a number average molecular weight of from about 300 to 20,000 and (ii) a second amine-containing polymer having a carbon-carbon backbone and formed by the process of polymerizing an organometallic compound-masked nitrogen containing monomer and a polymer chain monomer selected from the group consisting of ethylene, C3 to C25 alpha-olefins, and mixtures thereof, followed by deashing to remove the organometallic compound; wherein the amine-containing polymeric material has within its structure at least one reactive amino group selected from the group consisting of primary amino groups, secondary amino groups and mixtures thereof. The adducts possess dispersant, detergent, antioxidant and anti-corrosion properties.

L'invention porte sur des additifs pour carburants ou lubrifiants comprenant le produit de réaction d'au moins un composé de quinone et d'un matériau polymére contenant des amines et comprenant au moins un élément choisi dans un groupe comprenant (i) un premier polymère contenant une amine et dérivant d'un polymère d'hydrocarbure d'un poids moléculaire compris entre 300 et 20 000, et (ii) un deuxième polymère contenant une amine à squelette carbone-carbone, et formé par polymérisation d'un monomère contenant un azote masqué par un composé organométallique et d'un monomère à chaîne polymére choisi dans un groupe comprenant de l'éthylène, des alpha oléfines C3 à C25 et leur mélange, suivi d'un décendrage servant à éliminer les composés organométalliques. La structure du matériau polymère comporte au moins un groupe amino réactif choisi dans un groupe consistant en groupes amino primaires, en groupes amino secondaires et en leur mélange. Lesdits additifs ont des propriétés dispersives, détergentes, antioxydantes et anticorrosives.
