摘要 |
<p>Polyetherimide compositions of formula (1) are described wherein the polyetherimide compositions comprise a polyetherimide comprising a reacted combination of alkali metal salts comprising an alkali metal salt of a dihydroxy aromatic compound and an alkali metal salt of a monohydroxy aromatic compound with a bis(halophthalimide), wherein the alkali metal salt of the monohydroxy aromatic compound is included in an amount of more than 0 and less than 5 mole percent, based on the total moles of the alkali metal salts, and the polyetherimide has a weight average molecular weight greater than or equal to 43,000 Daltons. The polyetherimide exhibits lower levels of chlorine and chlorine end groups, lower levels of bis(halophthalimide) and bis(phthalimide), and low plate-out during manufacturing.</p> |
