Beschreibung
Zusammenfassung:	A homogeneous solid composition includes an aromatic epoxy resin and a poly(phenylene ether) having a number average molecular weight of 600 to 2000 atomic mass units and an average of 1.5 to 3 hydroxyl groups per molecule. The molecular weight and hydroxyl functionality of the poly(phenylene ether) allow it to be dissolved in the epoxy resin at relatively low temperature, and remain dissolved as the solution is cooled and solidified. The homogeneous solid composition facilitates incorporation of the poly(phenylene ether) into powder coating compositions that exhibit reduced water absorption in the cured state.
