Abstract: A polyetherimide composition comprising a polyetherimide manufactured by reaction of an alkali metal salt of a dihydroxy aromatic compound with a bis(halophthalimide) composition comprising, based on the weight of the bis(halophthalimide) composition, at least 15 wt. % of a 3,3?-bis(halophthalimide) of the formula from more than 17 wt. % to less than 85 wt. % of a 4,3?-bis(halophthalimide) of the formula and from more than 0 wt. % to less than 27 wt. % of a 4,4?-bis(halophthalimide) of the formula wherein R is para-phenylene.

Abstract: Improvements in compressor manufacture are achieved by utilizing polymeric components which retain at least 90% of their dimensions after being exposed to a mixture of refrigerants and/or lubricants for 30 days at 60° C. Polymeric materials include (i) polyetherimides, (ii) polyphenylene sulfides, (iii) polyketones, (iv) polysulfones, (v) liquid crystal polymers, and (vi) combinations thereof. Metal coatings on the polymers are the preferred embodiments for housings.

Abstract: Disclosed herein is an article comprising a lens having a width of 0.1 millimeters to 100 millimeters, a length of 0.5 millimeters to 500 millimeters, and a thickness of 0.2 millimeters to 5 millimeters; and the lens transmits light having a wavelength of 600 nanometers to 1600 nanometers, wherein the lens comprises a polymer and the polymer comprises a polyimide comprising structural units derived from specific combinations of compounds wherein the lens is transparent and dimensionally stable at a wall thickness of 0.2 millimeters to 5.0 millimeters and remains transparent and dimensionally stable after being (a) exposed to a precondition of 60° C./60% relative humidity for 120 hours and (b) then subjected to a lead free solder test having a peak temperature of 260° C. for up to 30 seconds.
