The present invention is directed to a microporous membrane contactor for degassing liquids at temperatures greater than (>) 60.degree. C. and at pressures greater than or equal (.gtoreq.) to 40 psig. The contactor has a microporous hollow fiber membrane adapted to withstand collapse and resist appreciable pore shrinkage or pore closure when subjected to liquid temperatures greater than (>) 60.degree.
