Patent ID: 8063125

Claim:
A phthalate-free plasticizer preparation comprising a) from 70 to 98% by weight of at least one aryl alkylsulfonate of the formula R 1 —SO 2 —O—R 2 and b) from 2 to 30% by weight of at least one diol dibenzoate of the general formula R 3 C(O)O—Y—O(O)CR 4 or of at least one dibenzyl dicarboxylate of the general formula R 3 CH 2 O(O)C—Z—C(O)OCH 2 R 4 or a mixture of the formulae R 3 C(O)O—Y—O(O)CR 4 and R 3 CH 2 O(O)C—Z—C(O)OCH 2 R 4 , where the total of the percentages by weight of all of the components of the preparation is 100% and in which R 1 is a straight-chain or branched C 1 -C 20 -alkyl radical, R 2 is a phenyl radical optionally substituted with C 1 -C 4 -alkyl or with halogen, Y is an alkylene radical optionally containing ether groups and having at least 2 carbon atoms, each of R 3 and R 4 independently of the other is a phenyl radical optionally substituted with C 1 -C 4 -alkyl or with halogen, and Z is a saturated or unsaturated, straight-chain or branched, cyclic or polycyclic C 2 -C 10 -hydrocarbon radical, where the total of the percentages by weight of all of the components in the plasticizer preparation is 100%.
