Abstract (en)
[origin: WO8302117A1] The softening points, intrinsic viscosities, and impact strength values of hydroxyl-terminated thermoplastic polyphenylene ether resins are improved when the resins are "capped" (i.e., reacted) with a triaryl phosphite. The reaction proceeds rapidly to a useful extent in the normal time the components pass through an extrusion press or molding machine.
