    Abstract: PROBLEM TO BE SOLVED: To provide a mixture containing an alkylbenzyl ester of a polycarboxylic acid.
    SOLUTION: The ester mixture is composed of a polyalkyl ester of an aromatic or aliphatic polycarboxylic acid, an alkylbenzyl ester of the aromatic or aliphatic polycarboxylic acid and a polybenzyl ester of the aromatic or aliphatic polycarboxylic acid. The ester mixture can be prepared by reacting the aromatic or aliphatic polycarboxylic acid with a benzyl alcohol and an aliphatic alcohol and removing reaction water. The ester mixture is used as a plasticizer for plastics.
