The polymerzation of linoleic acid, and of its ester, in the presence of carbonyl catalyst was studied under the following conditions ; catalyst concentration : 515%, temperature : 220300°C and time : 120 hr. The polymers were obtained in high yields and the maximum polymer content of the crude reaction products was about 65%. The polymer content of the product obtained from linoleic acid was smaller than that of the product from methyl linoleate under the same reaction conditions. The time required for the polymer content to reach 60% decreased with increase in the reaction temperature or in the amount of catalyst.<BR>The polymeric fractions separated from the products usually had darker color, higher acid number, and lower saponification number, than the original ester. The polymeric fractions contained mainly the dimer and a small proportions of polymers of higher molecular weight.<BR>From the results of analysis of the polymers, it is believed that the polymerization involves DielsAlder reaction and some other type of reaction.
