METHOD FOR PRODUCING POLYESTER TYPE FLEXIBLE POLYURETHANE FOAM, AND CATALYST COMPOSITION TO BE USED THEREFOR

摘要

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 C_1-6 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 C_1-2 alkyl group,an amine compound represented by the following formula (2):; ;in the above formula (2), R₆ is a C_2-6 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 C_1-4 alkyl group, and R₉ is a C_3-5 linear or branched alkylene group;a blowing agent; and a surfactant.
