  Thermoplastic polyamideimide copolymers are provided which are excellent in both heat stability and melt viscosity characteristics at a temperature of from about 300°C to about 400°C. The copolymers of the invention comprise Units A of the formula in an amount of about 50 mole %, Units B of the formula in an amount of about 15-48 mole % and Units C of the formula in an amount of about 35-2 mole %, wherein Z is a trivalent aromatic group having two of its three carbonyl groups attached to adjacent carbon atoms, a is 0 or 1, b is 0,1,2,3 or 4, R1 is alkyl (C1-4), R2 is selected from alkyl (C1-4), halo and nitro, c is an integer from 1 to 25 and X is chosen from - SO2 -CO- or -C(CH3)2-. The copolymers may be made by reacting diamines containing the Units B and C respectively, e.g. I and II, with trimellitic acid (or another aromatic tribasic carboxylic acid with two carboxyl groups attached to adjacent carbon atoms) in an organic polar solvent using a dehydrating catalyst - or alternatively the diamines may be reacted with the acid anhydride acid chloride using a hydrochloride scavenger, subsequently closing the ring of the polyamide-amic acid thus formed.

  We have been actively involved in the development of parallel approaches for the discovery of phosphine ligands. Our approach has been based on the incorporation of phosphine-containing amino acids into peptide sequences that are designed to have stable secondary structures. We have examined helical and turn secondary structures and have reported that alkylation of cyclopentenyl acetate with dimethylmalonate can be catalyzed in high enantiomeric excess (ee) with a beta-turn-based ligand. The importance of the peptide secondary structure was demonstrated through the synthesis of a series of peptide ligands where the nature of the turn-forming residues was probed. Additionally, other turn-forming units and a variety of different phosphine-containing amino acids have been examined for their ability to control the selectivity of the allylation reaction. This paper reports the results obtained through the examination of different turn motifs as well as different phosphine substitutions on the "best" turn sequence, Pps-Pro-D-Xxx-Pps.
