Low-hysteresis elastomer compositions using amino-substituted aryllithium polymerization initiators

A VULLCANIZABLE ELASTOMERIC COMPOUND AND PRODUCTS SUCH AS PNEUMATIC AND SIMILAR CHAMBERS ARE FORMED FROM A FUNCTIONALIZED POLYMER HAVING A FUNCTIONAL GROUP DERIVED FROM ANIONIC POLYMERIZATION INITIATOR. THE ANIONIC POLYMERIZATION INITIATOR UNDERSTANDS THE GENERAL FORMULA: WHERE R1 ARTS FROM THE GROUP CONSISTING OF HYDROGEN, RENTALS HAVING COMPOUNDS RENT FROM 1 TO APPROXIMATELY 12 CARBON ATOMS; ARALQUILES DISPOSING FROM 7 TO APPROXIMATELY 20 CARBON ATOMS; DIALKYLAMINES HAVING FROM 2 TO APPROXIMATELY 20 CARBON ATOMS; AND, DIALQUILAMINOALQUILOS HAVING FROM 3 TO APPROXIMATELY 20 ATOMS OF CARBON. AT LEAST ONE OF THE R1 DIALKYLAMINES AND DIALKYLAMINOALKYLS. METHODS OF THE PRESENT INVENTION INCLUDE THE FUNCTIONAL PREPARATION OF POLYMERS AND THE REDUCTION OF HYSTERESIS OF VULLCANIZABLE ELASTOMERIC COMPOUNDS.
