Abstract

Bis-Phenol A (BPA) can now be replaced in industrial processes by BPA substitutes. The BPA substitutes can have structures that are derivatives of BPA. The BPA substitutes can be used in preparing epoxy composition, polycarbonate compositions, and polysulfonate compositions or for other uses in place of BPA.

Claims (63)
