| | POLYETHERIMIDE Usage And Synthesis |
| 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. |
