    • This invention relates to a family of aliphatic esters having the following general structure: R 1 -O- C(0)-R 4 -C(O)-[-0-R 2 -O-C(O)-R 5 -C(O)-] m -O-R 3 in which: R 1 is selected from one or more of the groups consisting of H, linear and branched saturated and unsaturated alkyl residues of the C 1 -C 24 type, and polyol residues esterified with C 1 -C 24 monocarboxylic acids; R 2 comprises -CH 2 -C(CH 3 ) 2 -CH 2 - and C 2 -C 8 alkylene groups, and comprises at least 50% in moles of the said -CH 2 -C(CH 3 ) 2 -CH 2 - groups; R 3 is selected from one or more of the groups consisting of H, linear and branched saturated and unsaturated alkyl residues of the C 1 -C 24 type, and polyol residues esterified with C 1 -C 24 monocarboxylic acids; R 4 and R 5 comprise one or more C 2 -C 22 alkylenes and comprise at least 50% in moles of C 7 alkylenes; m lies between 1 and 20; at least one of R 1 and/or R 3 comprise polyol residues esterified with at least one C 1 -C 24 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 plasticisers 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.
    • 本发明涉及具有以下一般结构的脂族酯族:R 1 -O-C(O)-R 4 -C(O) - [ - O-R 2 -OC(O)-R 5 -C(O) mO-R 3,其中:R 1选自H,C1-C24型的直链和支链饱和和不饱和烷基残基中的一个或多个,和用C 1 -C 24单羧酸酯化的多元醇残基; R2包含-CH 2 -C(CH 3)2 -CH 2 - 和C 2 -C 8亚烷基,并且包含至少50%摩尔的所述-CH 2 -C(CH 3)2 -CH 2 - 基团; R3选自由C1-C24型的H,直链和支链饱和和不饱和烷基残基组成的组中的一个或多个,和被C 1 -C 24单羧酸酯化的多元醇残基; R 4和R 5包含一个或多个C 2 -C 22亚烷基并且包含至少50摩尔%的C 7亚烷基; m在1到20之间; R 1和/或R 3中的至少一个包括与至少一种选自硬脂酸,棕榈酸,9-酮硬脂酸,10-酮硬脂酸及其混合物的C 1 -C 24单羧酸酯化的多元醇残基。 这些酯特别适合用作各种类型的聚合物的增塑剂,例如聚氯乙烯(PVC)类型的乙烯基聚合物,热塑性弹性体和羟基酸聚酯,例如乳酸的聚酯。
