The new recently synthesized polymers - perfluorinated polyformaldehydes ha
ve long liquid range and low melting point. Due to the expected low upscatt
ering losses of ultracold neutrons, at low temperatures, these fluids may b
e good candidates for precision measurement of neutron lifetime by the meth
od of storage of ultracold neutrons in traps. (C) 1999 Elsevier Science B.V
