Abstract:
Oxalic acid diarylamides are described as useful monomers and comonomers in the polymerization of polycarbonates. The resin products resist degradation by ultra-violet light radiation. They can also be incorporated as comonomer or monomer in the polyester, polyester, polyether, polyethersulfone resins. They can also be used as UV stabilizers in the aforemetioned systems.
