Abstract
Poly(arylene ether phosphine oxide) (PEPO) with controlled molecular weights and amine end-groups was synthesized, and used as an adhesive, a coating material for adherend or a modifier for diglycidyl ether of bisphenol A (DGEBA)-based epoxy resins. Closely related poly(arylene ether sulfone) and commercial polyethersulfone, Udel® P-1700, were also utilized for comparison purposes. Adhesive behavior was measured via single lap shear samples as a function of coated polymer type, test temperature (R.T. and 100°C), and aging condition in boiling distilled water or 5% salt water. Flame resistance of PEPO and PEPO-modified epoxy resin was evaluated by TGA and a flame test. PEPO exhibited better adhesive properties than PES or Udel® P-1700. PEPO coating on an Al adherend markedly improved adhesive property of PES and Udel® even at 100°C, and after aging study failure mode changed from adhesive to cohesive with the PEPO. Aminophenyl terminated PEPO-modified epoxy resins also exhibited highly improved adhesive behavior and flame resistance, compared to control samples.
