Embodiments of the present disclosure are directed towards isocyanate reactive compositions that include a polyol and tris(4-hydroxyphenyl)methane alkoxylate.

Isocyanate reactive compositions

Embodiments of the present disclosure are directed towards β-hydroxyphosphonate functionalized polyols and isocyanate reactive compositions that include the β-hydroxyphosphonate functionalized polyol and a base polyol.

Beta-hydroxyphosphonate functionalized polyols

A reaction system for forming a step-growth polymerized sulfur-containing polyester polyol includes at least one sulfur-containing component selected from the group of a sulfur-containing polyol or a sulfur-containing polycarboxylic acid, an amount of the at least one sulfur-containing component being from 1 wt % to 60 wt %, at least one aromatic component selected from the group of an aromatic multi-functional ester, an aromatic multi-functional carboxylic acid, and an aromatic anhydride, an amount of the at least one aromatic component being from 1 wt % to 60 wt %, at least one simple polyol that excludes sulfur and is different from the sulfur containing polyol, an amount of the at least one simple polyol being from 0 wt % to 60 wt %, and at least one polymerization catalyst. The reaction system for forming the sulfur-containing polyester polyol has a sulfur content that is from 2 wt % to 20 wt %.

Polyurethane product with sulfur-containing polyester polyol

A mixture of octanols, nonanols and decanols is useful for the preparation of alkoxylates, which alkoxylates may be used as surfactants, which surfactants have surprisingly good biodegradability.

Readily biodegradable alkoxylate mixtures

An acrylic polyurethane coating composition, comprising an isocyanate component comprising at least one polyisocyanate trimer; and an isocyanate reacting mixture, the isocyanate reacting mixture comprising from 25 wt % to 80 wt % of an acrylic polyol and from 1 wt % to 30 wt % of a polyether polyol, based on a total weight of the acrylic polyurethane coating composition, the acrylic polyol having a solids content of at least 50 wt %, based on a total weight of the acrylic polyol, and the polyether polyol having a viscosity of less than 500 mPa*s at 25&#xb0; C. and a number average molecular weight greater than 300 and less than 700.
