A method of preparing an antioxidant polymer includes forming or obtaining a first polymer having reactive pendant groups, where the first polymer does not include cyclic anhydride repeat units, and derivatizing the first polymer with an antioxidant. Another method of preparing an antioxidant polymer includes forming or obtaining a first polymer having reactive pendant groups and derivatizing the first polymer with an antioxidant, where the antioxidant is attached to the first polymer by an acetal, amide, amine, carbamate, carbonate, ester, ether or thioether linkage or by a carbon-carbon bond. The invention is also directed to polymers that are generally prepared by these methods, compositions that include such polymers and methods of using such polymers.

Procédé de préparation d'un polymère anti-oxydant consistant à former ou à obtenir un premier polymère comprenant des groupes pendants réactifs, le premier polymère étant exempt d'unités répétées anhydrides cycliques, et à dérivatiser le premier polymère à l'aide d'un anti-oxydant. Un autre procédé de préparation d'un polymère anti-oxydant consiste à former ou à obtenir un premier polymère comprenant des groupes pendants réactifs et à dérivatiser le premier polymère à l'aide d'un anti-oxydant, ce dernier étant rattaché au premier polymère par l'intermédiaire d'une liaison acétal, amide, amine, carbamate, carbonate, ester, éther ou thioéther, ou par une liaison carbone-carbone. La présente invention se rapporte également à des polymères généralement préparés au moyen de ces procédés, à des compositions comprenant de tels polymères, et à des procédés de mise en oeuvre desdits polymères.
