Abstract: PURPOSE:To obtain the subject low smellable catalyst having a good catalytic activity, and useful as a catalyst for producing polyurethane molded products. CONSTITUTION:This catalyst is represented by the formula (n) is 8-12, preferably 9). The catalyst is obtained preferably e.g. by subjecting 8-diaminooctane, etc., to a reductive methylation reaction, etc. The catalyst is preferably used, when a polyol is reacted with a polyisocyanate compound such as 2,4-tolylene diisocyanate. For example, N,N,N',N'-tetramethylnonanediamine is preferably used as the catalyst.

Abstract: PURPOSE:To obtain the subject composition which can give a polyurethane foam with good thermal conductivity, friability and mold filling property by incorporating three tert. amine compounds each containing a specified ring structure. CONSTITUTION:The objective composition is obtained by mixing three tert. amine compounds each containing a ring structure in the molecule and represented by formula I (wherein R1 and R2 are each 1-3C alkyl or dimethylaminoalkyl or hydroxyalkyl with 1-3C alkyl), formula II (wherein R3 and R4 are each 1-3C alkyl or cyclohexyl) and formula III (wherein R5 is H or 1-C alkyl; R is 1-4C alkyl or hydroxyalkyl). The mixing ratio is such that 5-20wt.% compound of formula I, 5-20wt.% compound of formula II and 60-90wt.% compound of formula III are mixed with each other. Only when a catalyst containing all of these three compounds is used, a urethane foam with good thermal conductivity, friability and mold filling property can be produced.

Abstract: PURPOSE:To obtain the subject foam, excellent in adhesion and mechanical properties especially at low temperatures by respectively using water as a foaming agent and one or more tertiary amino-alcohols as a polyol component. CONSTITUTION:The objective foam is obtained by reacting (A) a polyisocyanate component with (B) a polyol component containing one or more tertiary amino- alcohols expressed by formula I [R1 is 2-24C alkylene, alicyclic alkylene, cycloalkylene, arylene, aralkylene or (CH2CH2O)p-(CH2CH2)q [(p) is 0 or a positive number; (q)is a positive number{9147/28}; R2 is 1-24C alkyl, aryl or aralkyl; n is a positive number of 1-50] as part or all thereof using water as a foaming agent.

Abstract: PURPOSE:To obtain the subject new non-shift type catalyst consisting of a specific compound having strong catalyst activity and reduced in amount used without shifting to a surface of resin or vaporization after the reaction. CONSTITUTION:The aimed catalyst consisting of a compound expressed by the formula (R is H or methyl; n is 0-3). The aimed catalyst is obtained by adding ethylene oxide or propylene oxide to N-methyl-4-hydroxy-piperidine using potassium hydroxide as a catalyst.
