摩耗防止性の改善のための水素結合形成性の官能性を有するポリマー

Japanese Patent JP4881293

B2

The invention relates to lubricating oil formulations comprising copolymers or graft copolymers produced by radically polymerising polymerisable monomers and, in addition comprising long-chain ethylenically unsaturated compounds containing alkyl, in particular acrylate or methacrylate substitutes provided with hydrogen-bridge donator functions. The monomer exhibiting a hydrogen-bridge donator property is contained, according to said invention, in the polymer backbone or in graft side branches. Apart from the polymers containing monomers provided with hydrogen-bridge donator functions, said invention relates to polymers containing monomers simultaneously carrying donator and acceptor functions. It was found that the hydrogen-bridge donator functions of a polymer, in particular a simultaneous availability of the hydrogen-bridge donator and acceptor functions produce the positive effects on the anti-wear protection and on a detergency and dispersancy action. The inventive polymers are suitable, in the form of additives, for lubricating oil formulations, for example for motor oils or hydraulic fluids exhibiting an improved anti-wear behavior.
