Provided is a solution for forming a surface protective resin member, containing: a fluorine-containing acrylic resin having a hydroxyl value of 40 to 280; a fluorine-free acrylic resin having a hydroxyl value of 40 to 280; and a polyether polyol or a polyester polyol.

An article is prepared by injection molding, wherein the article is formed from a hydrophilic thermoplastic polyurethane composition, wherein the thermoplastic polyurethane composition comprises the reaction product of a hydroxyl terminated polyol intermediate component, an aliphatic isocyanate component, and, optionally, a chain extender component. For injection molding, the hydrophilic thermoplastic polyurethane has a crystallization temperature measured by dynamic scanning calorimetry of at least 75 C.

A curable composition for making polyisocyanurate comprising products obtained by combining and mixing at an isocyanate index of at least 100 at least a polyisocyanate composition, a polytetrahydrofuran polyol (P-THF) having average molecular weight in range 1000-5000 g/mol as toughening agent and diols having an average molecular weight <1000 g/mol.

An article is prepared by injection molding, wherein the article is formed from a hydrophilic thermoplastic polyurethane composition, wherein the thermoplastic polyurethane composition comprises the reaction product of a hydroxyl terminated polyol intermediate component, an aliphatic isocyanate component, and, optionally, a chain extender component. For injection molding, the hydrophilic thermoplastic polyurethane has a crystallization temperature measured by dynamic scanning calorimetry of at least 75? C.

Polyester polyols made from thermoplastic polyesters are disclosed. The polyols can be made by heating a thermoplastic polyester such as virgin PET, recycled PET, or mixtures thereof, with a glycol to give a digested intermediate, which is then condensed with a dimer fatty acid to give the polyol. The invention includes a polyester polyol comprising recurring units of a glycol-digested thermoplastic polyester and a dimer fatty acid. The polyester polyol can also be made in a single step by reacting the thermoplastic polyester, glycol, and dimer acid under conditions effective to produce the polyol. High-recycle-content polyols having desirable properties and attributes for formulating polyurethane products, including aqueous polyurethane dispersions, can be made. The polyols provide a sustainable alternative to bio- or petrochemical-based polyols.

An isocyanate composition according to the present invention contains: a difunctional or more-functional isocyanate compound; and 1.0 ppm by mass to 1.010.sup.4 ppm by mass, based on the isocyanate compound, of a compound having at least one unsaturated bond excluding unsaturated bonds constituting an aromatic ring, the compound being different from the isocyanate.
