| titleOfInvention | Process for producing polyurethane foam |
| abstract | A process for producing a polyurethane foam, comprising reacting an organic polyisocyanate component with a polyol component with the use of water as a foaming agent in the presence of a catalyst, wherein at least 30 wt.% of the polyol component consists of a lactone polyol of 20 to 350 KOHmg/g hydroxyl value being liquid at ordinary temperature, obtained by ring opening copolymerization of e -caprolactone and w -valerolactone used in an e -caprolactone/ w -valerolactone molar ratio of 80/20 to 20/80 with the use of a low-molecular-weight compound having at least two active hydrogens as an initiator and wherein the hydroxyl value of the polyol component is in the range of 40 to 400 KOHmg/g. Thus, a soft polyurethane foam excelling in mechanical properties can be produced with the use of only water as a foaming agent without the use of as a foaming agent, chlorofluorocarbons causing ozone layer destruction and further without the use of low-boiling-point organic solvents inviting the danger of firing. |
