| titleOfInvention | Process for producing polyurethane foam |
| abstract | The present invention provides a process for producing a polyurethane foam, which comprises allowing an organic polyisocyanate component to react with a polyol component in the presence of a catalyst with water as a foaming agent, wherein the polyol component comprises at least 30% by weight of a copolymerized lactone polyol having a hydroxyl value of 20 to 350 KOHmg/g and being in the form of a liquid at an ordinary temperature, the copolymerized lactone polyol is obtained by ring opening copolymerization of ε-caprolactone and δ-valerolactone in a molar ratio [ε-caprolactone/δ-valerolactone] of 80/20 to 20/80 with a low molecular weight compound having at least two active hydrogen groups as an initiator; and the hydroxyl value of the polyol component is 40 to 400 KOHmg/g. Thus, a soft polyurethane foam excellent in mechanical properties can be produced with the use of water only 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 fire. |
