TITLE: NOVEL CARBOXYLIC ACID ACYLATING AGENTS, DERIVATIVES THEREOF, CONCENTRATE AND LUBRICANT COMPOSITIONS CONTAINING THE SAME, AND PROCESSES FOR THEIR PREPARATION INVENTOR: Norman Anthony Meinhardt and Kirk Emerson Davis ABSTRACT OF THE DISCLOSURE: Carboxylic acid acylating agents are derived from poly-alkenes such as polybutenes, and a dibasic, carboxylic reactant such as maleic or fumaric acid or certain deriva-tives thereof. These acylating agents are characterized in that the polyalkenes from which they are derived have a Mn value of about 1300 to about 5000 and a Mw/Mn value of about 1.5 to about 4. The acylating agents are further charac-terized by the presence within their structure of at least 1.3 groups derived from the dibasic, carboxylic reactant for each equivalent weight of the groups derived from the poly-alkene. The acylating agents can be reacted with a further reactant subject to being acylated such as polyethylene polyamines and polyols (e.g., pentaerythritol) to produce derivatives useful per se as lubricant additives or as intermediates to be subjected to post-treatment with various other chemical compounds and compositions, such as epoxides, to produce still other derivatives useful as lubricant additives.

Products produced by these processes have enhanced dispersion, coating, adhesion, and plasticizing characteristics as a result of the lack of any steric hinderance of these polyoxyalkylene phosphonates.

IRON BASED POWDER COMPOSITIONS CONTAINING NEW BINDERS / LUBRICANTS.

LAS COMPOSICIONES METALURGICAS, EN POLVO, BASADAS EN HIERRO SE PRODUCEN MEZCLANDO POLVO BASADO EN HIERRO CON UN AMALGAMADOR/LUBRICANTE MEJORADO QUE COMPRENDE ACIDO ORGANICO DIBASICO Y UNO O MAS COMPONENTES ADICIONALES TALES COMO POLIETERES SOLIDOS, POLIETERES LIQUIDOS, Y RESINA ACRILICA. ESTOS NUEVOS AMALGAMADORES/LUBRICANTES IMPARTEN UNA O MAS PROPIEDADES MEJORADAS A LAS COMPOSICIONES EN POLVO Y REDUCEN LA FUERZA DE EYECCION REQUERIDA PARA ELIMINAR LAS COMPOSICIONES DE LOS MOLDES Y DE LOS TROQUELES. IRON BASED METALLURGICAL, POWDER COMPOSITIONS ARE PRODUCED BY MIXING IRON BASED POWDER WITH AN IMPROVED AMALGAMATOR / LUBRICANT COMPRISING ORGANIC DIBASIC ACID AND ONE OR MORE ADDITIONAL COMPONENTS, SUCH AS SOLID POLYETHERS, POLYETHRES AND ACRYLIC. THESE NEW AMALGAMADORES / LUBRICANTS IMPROVE ONE OR MORE IMPROVED PROPERTIES TO POWDER COMPOSITIONS AND REDUCE THE EJECTION FORCE REQUIRED TO ELIMINATE THE COMPOSITIONS OF MOLDS AND DIES.
