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.

Water-based stains are based on an oil-in-water emulsion having a binder that includes, consists of, or consists essentially of drying oil combined with a non-aqueous polymer dispersion. The compositions can be tinted using traditional water-based pigment dispersions, yet the overall hydrophobicity results in minimal interaction with the polar cellulosic structure of wood.

A conductive polymeric composition includes, based on a total weight of the conductive polymeric composition, 0.1 wt % to 10 wt % of carbon nanotubes, 0.2 wt % to 4 wt % of a first component, 0.1 wt % to 4 wt % of a second component made by esterification of a C.sub.16-C.sub.30 fatty acid with a polyol compound, and the balance being a polymeric component. When the first component is a first polymer obtained from polycondensation of an aromatic diacid compound and an aliphatic glycol compound, the polymeric component is a polyester. When the first component is a second polymer obtained from polycondensation of a lactam compound, a diamine compound and a dicarboxylic acid compound, the polymeric component is a polyamide.
