摘要： A METHOD OF DECONTAMINATING HYDROCARBONS USED AS SOLVENTS AND MONOMERS IN THE PRODUCTION OF SYNTHETIC RUBBER BY STEREOSPECIFIC POLYMERIZATION FROM CYCLOPENTADIENE CONSISTING IN TREATING A MIXTTURE OF SAID HYDROCARBONS AND CYCLOPENDADIENE WITH CYCLIC KETONES IN THE PRESENCE OF A CATALYST WHICH IS AN ALKALI METAL HYDROXIDE OR AN ANION-EXCHANGE RESIN IN THE (OH-) FORM TO OBTAIN A FULVENE,WHEREAFTER THE HYDROCABONS ARE DISTILLED OFF FROM THE MIXTURE THUS PRODUCED. THIS METHOD IS SIMPLE AND PERMITS INEXPENSIVE CATALYSTS TO BE USED. THE METHOD IS EFFECTIVE SINCE IT ELIMINATES LOSSES OF CATALYSTS AND CYCLIC KETONES.
