  • Hybrid polyols based on natural oil polyols
    Patent number: 11098158
    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.

  • Biorenewable high performance polyester polyols
    Patent number: 10941240
    Abstract: This invention provides a process for manufacturing high performance polyester polyols with high proportion of renewable content derived from biological sources. The polyester polyols with high content of renewable biological materials produced according to the present invention display no color or odor issues and are used in the manufacture of two component polyurethanes, thermoplastic urethanes, polyurethane dispersions and polyester and polyester/urethane acrylates with outstanding physical properties.
