ABSTRACT:
A method for the preparation of a flexible, open-celled, urethane foam which comprises reacting at least one isocyanate and at least one polyol in the presence of at least one catalyst and an epoxidized soybean oil, wherein each polyol is a saturated polyether polyol. A further aspect of the present invention provides a pre-formation method for the preparation of a flexible, open-celled, urethane foam, the method comprising reacting at least one isocyanate and at least one polyol in the presence of at least one catalyst and about 7 phR to about 25 phR of an epoxidized soybean oil, wherein each polyol is a saturated polyester polydol. Flexible, open-celled urethane foams prepared in accordance with the methods set forth previously are also included in the present invention.
