Homogeneous blends of poly (parabanic acid) resins and aromatic polyether sulfones and terephthalate polyesters are obtained by plasticizing the poly (parabanic acid) resins. The poly (parabanic acid) resins are plasticized with conventional plasticizers for these polymers, such as aromatic polyesters, N,N-dialkyl aromatic sulfonamides, aromatic nitriles, aromatic sulfones and aromatic sulfoxides. Additionally it has been found that polyether sulfones which are free of aliphatic groups are also plasticizers for the poly (parabanic acid) resin. |
