Abstract:
1. A polyetherimide product comprising a polyetherimide composition comprising a reacted combination of alkali metal salts and a bis(halophthalimide): (a) the combination of alkali metal salts comprising an alkali metal salt of a dihydroxy aromatic compound having the formula an alkali metal salt of a monohydroxy aromatic compound having the formula wherein M Z 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; with (b) the bis(halophthalimide) of the formula wherein R is selected from an aromatic hydrocarbon group having 6 to 27 carbon atoms, a halogenated derivative thereof, a straight or branched chain alkylene group having 2 to 10 carbon atoms, a halogenated derivative thereof, a cycloalkylene group having 3 to 20 carbon atoms, a halogenated derivative thereof, an aromatic hydrocarbyl moiety having from 1 to 6 aromatic groups, and a divalent group having the formula wherein Q each X is independently selected from fluoro, chloro, bromo, and iodo; wherein the polyetherimide composition has a weight average molecular weight greater than or equal to 43,000 Daltons and comprises structural units having the formula wherein n is greater than 1, and each R is the same or different, each Z wherein the polyetherimide composition has a plate-out weight of less than 1.1 mg, when determined using 200 shots from a 100° F. (37.8° C.) mold having the dimensions of 5×6×0.16 inches (12.7×15.2×0.4 cm); and wherein the polyetherimide composition comprises less than 350 ppm of residual bis(halophthalimide, based on the total weight of the polyetherimide composition.
