    Abstract: This invention relates to a family of aliphatic esters having the following general structure: R1—O—C(O)—R4—C(O)-[—O—R2—O—C(O)—R5—C(O)-]m—O—R3 in which: R1 is selected from one or more of the groups consisting of H, linear and branched saturated and unsaturated alkyl residues of the C1-C24 type, and polyol residues esterified with C1-C24 monocarboxylic acids; R2 comprises —CH2—C(CH3)2—CH2— and C2-C8 alkylene groups, and comprises at least 50% in moles of the said —CH2—C(CH3)2—CH2— groups; R3 is selected from one or more of the groups consisting of H, linear and branched saturated and unsaturated alkyl residues of the C1-C24 type, and polyol residues esterified with C1-C24 monocarboxylic acids; R4 and R5 comprise one or more C2-C22 alkylenes and comprise at least 50% in moles of C7 alkylenes; m lies between 1 and 20; at least one of R1 and/or R3 comprise polyol residues esterified with at least one C1-C24 monocarboxylic acid selected from the group consisting of stearic acid, palmitic acid, 9-ketostearic acid, 10-ketostearic acid and mixtures thereof. These esters are particularly suitable for use as plasticizers for various types of polymers such as for example vinyl polymers of the polyvinyl chloride (PVC) type, thermoplastic elastomers, and hydroxy acid polyesters, for example polyesters of lactic acid.
