A method for producing a rigid foamed synthetic resin, which comprises reacting a polyol with a polyisocyanate compound in the presence of water, a catalyst and a fluorine-containing compound of the formula 1: n R f —O—(A-O) n —R Formula 1 n where in the formula 1, R f is a C 2-27 fluorine-containing organic group, n is an integer of from 1 to 100, A is an alkylene group having a carbon number in the straight chain portion between bonds of from 2 to 4, provided that when n is from 2 to 100, the plurality of A may be the same or different, and R is a hydrogen atom, a C 1-18 alkyl group or a C 1-18 acyl group. |
