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. |
