Abstract

2-Hydroxy-3-alkylsulfoxypropyl-1 esters of arene polycarboxylic acids.

Claims

1. Poly (2-hydroxy-3-alkylsulfoxypropyl-1)_n esters of arene polycarboxylic acids wherein the said esters are of the formula ##STR10## wherein n is 2 to 6, R is an n-valent radical derived from benzene, biphenyl, naphthalene, anthracene or phenanthrene wherein R can be substituted by nitro, halogen and alkoxy of 1 to 12 carbon atoms and R'"'"' is selected from the group consisting of alkyl moieties containing from 1 to 22 carbon atoms, and aralkyl moieties, alkylated aryl moieties and cycloalkyl moieties containing 4 to 40 carbon atoms, the ring radicals of said moieties being selected from the group consisting of phenyl, biphenyl and cyclohexyl radicals, where R'"'"' can be substituted with nitro, halogen and alkoxy of 1 to 12 carbon atoms.

2. The compound of claim 1 which is bis-(3-dodecylsulfoxy-[3]2-hydroxypropyl) terephthalate.
