Title: HYBRID POLYOLS BASED ON NATURAL OIL POLYOLS
Abstract:
This invention relates to hybrid polyols useful in the manufacture of polyurethane. The hybrid polyols of the present invention is derived by copolymerizing or grafting a traditional polyester polyol onto a natural oil polyol. In the preferred embodiment of the present invention, the traditional polyester polyol grafted onto natural oil polyol contains a high level of bio- renewable content. The hybrid polyols of the present invention with high level of bio-renewable content is useful in the manufacture of polyurethane either alone or in combination with polyester polyol or polyether polyol derived from petrochemical sources.
