Abstract: Polymers containing post-reacted hindered phenol anti-oxidant functionality as viscosity index (VI) improvers for high temperature service, particularly for lubricating oils used in diesel engines.
Abstract: The invention is concerned with novel unsaturated compounds having extremely low volatility having a single monoethylenically unsaturated group of the formula H.sub.2 C = C < whereby they are capable of polymerization to produce linear homopolymers and copolymers with copolymerizable monomers containing such a group, and having autoxidizable characteristics by virtue of a different type of unsaturated group. These new compounds are useful for the production of polymers, alone or in admixture with other polymers or monomers to modify the characteristics of the components of the mixture. They are useful in coating or impregnating compositions and/or in the molding, casting, or otherwise forming of shaped articles.
Abstract: Compositions comprising a blend of poly(alkylene terephthalates) and an impact modifier which is a multi-phase composite interpolymer comprising a crosslinked acrylic first stage which also contains graftlinking monomer and a final rigid thermoplastic phase.

Abstract: Polymers containing anti-oxidant functionality have been found to be useful as viscosity index (VI) improvers for high temperature service. The anti-oxidant moiety prevents extensive oxidative decomposition of the polymer making the polymers particularly useful with lubricating oils used in diesel engines.
