Zusammenfassung:	A RUBBER DERIVATIVE COMPRISES A COORDINATION COMPOUND OF A NATURAL OR SYNTHETIC RUBBER CONTAINING DOUBLE BONDS AND/OR EPOXY OR OTHER GROUPS CONTAINING AN ELECTRONEGATIVE ATOM AND PREFERABLY HAVING A WEIGHT AVERAGE MOLECULAR WEIGHT OF FROM 20,000 TO 90,000, MORE PREFERABLY , 20,000 TO 85,000, ESPECIALLY ABOUT 80,000, WITH AN ALKALI OR ALKALINE EARTH METAL . THE DERIVATIVES MAY BE MADE BY DISSOLVING A RUBBER CONTAINING DOUBLE BONDS AND/OR EPOXY OR OTHER GROUPS CONTAINING AN ELECTRONEGATIVE ATOM OR ATOMS AND HAVING AT LEAST A COMPONENT WITH A WEIGHT AVERAGE MOLECULAR WEIGHT IN THE RANGE OF FROM 20,000 TO 90,000, MORE PREFERABLY , 20,000 TO 85,000, ESPECIALLY ABOUT 80,000, IN A POLAR SOVENT , ADDING TO THE SOLUTION AN AT LEAST EQUIVALENT AMOUNT OF POWDERED ALKALI METAL AND/OR ALKALINE EARTH METAL HYDROXIDE AND/OR CARBONATE , OPTIONALLY TOGETHER WITH A DESICCANT, IF THE SOVENT IS NOT WATER-FREE, STIRRING THE MIXTURE UNTIL A COORDINATION COMPOUND BETWEEN THE RUBBER AND THE METAL ATOMS HAS FORMED AND SEPARATING THE COORDINATION COMPOUND FROM THE SOLVENT.
