Abstract

On greffe un polymère, sur un squelette d'hydrocarbure polymère, un monomère d'azote de vinyle polymérisable à radical libre, la greffe ayant lieu en présence d'un solvant aromatique à substitution d'hydrocarbure aliphatique, capable d'un transfert de chaîne d'atomes d'hydrogène à radical libre. Le polymère à base d'hydrocarbure modifié trouve une utilité en tant qu'additif pour huiles lubrifiantes, notamment en tant que dispersant et agents améliorant la viscosité pour des huiles de moteur.
