摘要

AbstractThermal expansion property at 288°C and methylene chloride resistance of poly(2,6‐dimethyl‐1,4‐phenylene ether (PPE)/epoxy laminate were found to be affected by the functionality on PPE resin. Nonlofting PPE/epoxy laminates were prepared with the PPE grafted with fumaric acid or the PPE having (di‐n‐butylamino) methyl substituent on the polymer backbone. Employing vacuum‐vented PPE extrudate or phenol‐redistributed PPE was also effective in improving the PPE/epoxy laminate properties. Attempts to preparing a real PPE/epoxy interpenetrating network as the matrix material for the laminate were also made by incorporating both PPE crosslinker and epoxy curing catalysts in the same formulation. © 1993 John
