ABSTRACT:
This invention relates to novel polyether polyols which are prepared by alkoxylation of renewable resource materials, and particularly cashew nutshell liquid (CNSL), and to a process for the preparation of these novel polyether polyols. This invention also relates to flexible polyurethane foams prepared from these long chain polyether polyols, and to a process for the production of these flexible polyurethane foams.
