Claims
- 1. A miscible blend comprising a polyarylate and a polycarbonomide, said polycarbonomide comprising recurring units having the formula: ##STR27## wherein Ar is an aromatic carbocyclic radical consisting of two aromatic nuclei linked through a divalent bridging group and Ar' is an aromatic carbocyclic radical consisting of a plurality of aromatic nuclei linked through isopropylidene moieties, and wherein said polycarbonomide comprises greater than about 5 wt. % isopropylidene moieties.
- 2. The miscible blend of claim 1 wherein Ar' is ##STR28##
- 3. The miscible blend of claim 2 wherein said divalent bridging group is --CO--.
- 4. The miscible blend of claim 3 wherein the polyarylate is an arylate-carbonate copolymer.
- 5. A miscible blend comprising a polyarylate and a polycarbonomide, said polycarbonomide comprising units derived from polycarboxylic acids selected from the group consisting of ##STR29## and units derived from ##STR30## with the proviso that said polycarbonomide comprises greater than about 5 wt. % isopropylidene moieties.
- 6. A miscible blend comprising a polyarylate and a polycarbonomide, said polycarbonomide comprising units derived from ##STR31## and units derived from ##STR32## with the proviso that said polycarbonomide comprises greater than about 5 wt. % isopropylidene moieties.
- 7. The blend of claim 6 wherein the wt. % of said isopropylidene moieties is greater than or equals the quantity (8-3(imide)), wherein (imide) is the fraction of imide groups in said polycarbonomide.
- 8. The blend of claim 6 wherein the polyarylate is an arylate-carbonate copolymer.
- 9. A miscible blend of a polyarylate and a polycarbonomide comprising recurring units of the following formula: ##STR33## wherein said polycarbonomide comprises greater than about 5 wt. % isopropylidene moieties.
