  • Patent number: 4959488
    Abstract: Polyfunctional hexasubstituted benzene derivatives wherein at least three of the substituents are saturated carbon chains having from 1 to 21 carbon atoms and functional groups containing hetero functionalities at the ends of the carbon chains and the remainder of the 6 substituents are either saturated carbon chains containing from 1 to 21 carbon atoms or saturated carbon chains containing from 1 to 21 carbon atoms having a functional group including a hetero functional group containing N, O, S, P, or Si at the end of the chains.
