Patent ID: 8912272

Claim:
A moisture resistant composition comprising a polymeric component consisting essentially of: a) 25 weight percent, based on the total weight of the composition, of a polyetherimide copolymer made from a monomer mixture comprising 3,3′ bisphenol-A dianhydride (BPADA), and 4,4′-diaminodiphenyl sulfone (DDS); and b) 66 weight percent, based on the total weight of the composition, of polyetheretherketone (PEEK); the moisture resistant composition further comprising c) 9 weight percent, based on the total weight of the composition, of a silica filler; wherein, in conditions of dry atmosphere/260° C. and 60° C./60% relative humidity, articles having thicknesses of 2-3 mm, molded from the moisture resistant composition, each exhibit no popcorning and a warpage of less than or equal to 0.5 mm.
