ABSTRACT:
The present invention comprises novel single-functional and mixtures of multi-functional oligomeric performance additive compounds having one or more components of Structure A R1 ? ? ##STR1## (The definitions of R, Z1, Z2, Z3, A1, A2, A3 and y are given in the Summary Section), their uses and polymeric compounds and compositions containing them which have enhanced oxidative stabilities, enhanced ultraviolet (UV) and light stabilites and/or enhanced flame retardance. An example is the bis sulfonic acid bispotassium salt reaction product from an oligomeric caprolactone diol (TONE.RTM. 260), 2-sulfobenzoic acid anhydride and potassium carbonate, and use of this product, at levels up to about 3.0%, in a general purpose bisphenol A polycarbonate resin, to enhance the fire resistance or flame retardance of the polycarbonate resin.
