  • Method of preparing polyester carbonates
    Patent number: 4286083
    Abstract: A novel process is disclosed for the preparation of copolyesters containing both carboxylate and carbonate groups. The process comprises reacting a carbonyl halide with a difunctional carboxylic acid and a dihydroxy compound in a reaction media which comprises water and a water immmiscible solvent in the presence of a tertiary amine.

  • Preparation of polyester carbonates from polyanhydride ester intermediates
    Patent number: 4130548
    Abstract: A novel process is disclosed for the preparation of polyester carbonates containing both carboxylate and carbonate groups. The process is based on the making of a mixed polyanhydride ester of a dibasic acid which is reacted with a dihydroxy compound to form a hydroxy containing intermediate that is subsequently transformed into a polyester carbonate by means of a carbonate forming reagent.

  • Method for making polyetherimides
    Patent number: 4011198
    Abstract: A process for making polyetherimides is provided by melt polymerizing a mixture of organic diamines and certain aromatic bis(etherdicarbonyl) compounds such as aromatic tetra-carboxylic acids and dianhydrides thereof. The polyetherimides can be made in a continuous manner. Fillers can be incorporated into the polyetherimides to produce high performance composites.
