POLYETHERIMIDE Chemical Properties,Usage,Production

Uses

Polymer blends of PEI and polyethylene glycol (PEG) have been used to prepare carbon molecular sieves. PEI has been used as matrix in the fabrication of various composites:

  • PEI/ BaTi4O9 composites,
  • PEI/glass fiber composites,
  • Nanocomposite PEI/TiO2-sulfonated polymer membranes,
  • Nanoparticles coated PEI-polyurethane (SiO2/PEI-PU) nanofibrous composite membranes,
  • Single walled nanotubes (SWNTs)/PEI nanocomposites.

General Description

Polyetherimide (PEI) is a thermoplastic polymer, containing cyclic amide. PEI is a polyimide condensation polymer derived from the bifunctional carboxylic anhydrides and primary diamines.

Synthesis

One method of preparing a polyetherimide is by polymerization of an alkali metal salt of a dihydroxyaromatic compound (e.g., a disodium salt of bisphenol A (BPA-Na2)) with bis(halogenated phthalimide). The molecular weight of the resulting polyetherimide can be controlled in two ways. The first is to use a molar excess of bis(halogenated phthalimide) relative to the alkali metal salt of the dihydroxyaromatic compound. The second is to prepare bis(halogenated phthalic anhydride) in the presence of a monofunctional compound (e.g., phthalic anhydride) to form a capping agent. The phthalic anhydride is reacted with a portion of an organic diamine to form monohalogeno-bis(phthalimide). The monohalogenobis(phthalimide) is used as a capping agent in the polymerization reaction step by reacting with the phenol salt end groups in the growing polymer chain.
