  • Formation of discrete polyalkylene carbonate particles by solvent/non-solvent precipitation
    Patent number: 5041469
    Abstract: Discrete, non-agglomerating particles of polyalkylene carbonate are produced by solvent/non-solvent precipitation using certain solvent/non-solvent systems. The free-flowing particles obtained are from 30 to 3000 microns in diameter and are suitable for use in a variety of applications, particularly the preparation of foamed articles.

  • Preparation of discrete particles of polyalkylene carbonate
    Patent number: 4853462
    Abstract: The selection of the proper solvent systems for polyalkylene carbonates which completely dissolve the polymer at high temperatures but are non-solvents at lower temperatures allows one to obtain discrete particles of the polymers suitable for many applications, processing and handling. The particles size can be controlled from about 30 to about 3000 microns in diameter.

  • Melt processable aliphatic polycarbonate terpolymers
    Patent number: 4851507
    Abstract: The addition of a small amount of a second epoxide to the copolymerization of ethylene oxide or propylene oxide with carbon dioxide can give a melt processable polyalkylene carbonate terpolymer which can be processed without extensive thermal decomposition. This invention has particular utility in thermoplastic applications such as injection molding, blow molding, and film manufacture.

  • Polyalkylene carbonate hot melt adhesive
    Patent number: 4833036
    Abstract: Copolymers or terpolymers of carbon dioxide and at least one epoxide are found to be useful in formulations for adhesive compositions. Polarity due to the carbonate group and non-polarity due to the alkylene groups in the resulting polyalkylene carbonates makes it possible to adhere a large number of different surfaces such as steel, aluminum, fluoropolymers, and polyesters to themselves or to each other.
