To provide a method for producing a low-odor polyester-type flexible polyurethane foam which is excellent in formability and free from scorch in the interior of the foam, and further discharges substantially no volatile amine compound from a product, in the production of a polyester-type flexible polyurethane foam, and to provide a catalyst composition to be used for the production method.
A polyester-type flexible polyurethane foam is produced by a process which comprises reacting a polyester polyol with a polyisocyanate, in the presence of a catalyst composition containing one or more amine compounds selected from the group consisting of an amine compound represented by the following formula (1):
in the above formula (1), R1 is a C1-6 linear or branched alkyl group, and each of R2, R3, R4 and R5 which are independent of one another, is a hydrogen atom or a C1-2 alkyl group,
an amine compound represented by the following formula (2):
in the above formula (2), R6 is a C2-6 linear or branched alkylene group, and an amine compound represented by the following formula (3):
in the above formula (3), each of R7 and R8 which are independent of each other, is a C1-4 alkyl group, and R9 is a C3-5 linear or branched alkylene group; a blowing agent; and a surfactant.
