Blends of an ethynyl terminated imidothioether with ethynyl terminated arylene ether oligomersAn evaluation has been undertaken of blends of a novel ethynyl-terminated imidothioether with Udel P1700 polysulfone and ethynyl-terminated arylene ether oligomers. Good to excellent processability was obtained with these blends using compression molding; the cured blends displayed poor-to-good resistance to chloroform and low-to-moderately high fracture toughness, depending on the blends' crosslink density. The flexural strength and modulus of unidirectional carbon graphite laminates prepared with the blended resins were good.
