The thermoplastic polyurethane elastomers described herein exhibit higher glass transition temperatures and higher Shore A hardness compared to thermoplastic polyurethane elastomers synthesized from similar polyester diols made from virgin monomers that do not contain nitro substitution.

The invention is directed to biomedical polyurethanes. The invention is particularly directed to biomedical polyurethanes with improved biodegradability and to an improved preparation of the biomedical polyurethanes. In particular the present invention provides a biomedical polyurethane having the formula (A-B-C-B).sub.n, wherein A denotes a polyol, B denotes a diisocyanate moiety, C denotes a diol component and n denotes the number of recurring units, and wherein the B-C-B segment is bioresorbable.

Disclosed herein are a recoatable coating composition suitable for use in in-mold coating processes, methods of coating substrates with such compositions, and coated substrates obtained by said method.

A display film includes a transparent polymeric substrate layer and a transparent energy dissipation layer disposed on the transparent polymeric substrate layer. The transparent energy dissipation layer includes cross-linked polyurethane and a polyacrylate polymer. The transparent energy dissipation layer has a glass transition temperature of 27 degrees Celsius or less and a Tan Delta peak value of 0.5 or greater.

Disclosed are methods of forming foam comprising: (a) providing a foamable composition comprising an isocyanate, a polyol and a physical blowing agent comprising at least about 50% by weight of hydrohaloolefin, including trans1233zd, and wherein the polyol comprises a polyol or mixture of polyols such that the hydrohaloolefin, including trans1233zd, has a solubility in said polyol of less than about 30%; and (b) forming a foam from said foamable composition.

A polymerizable composition for optical materials of the present invention includes a polymer (a) comprised of one or more compounds selected from compounds represented by the following General Formulas (1) to (4), a compound (b) of which light absorption characteristics vary by sensing changes in environment; and a polymerization reactive compound (c) (except for the polymer (a)). ##STR00001##

Provided is a composition comprising one or more epoxy phosphate esters wherein the structure comprises two or more polyester linkages. Also provided is a method of making the epoxy phosphate esters that comprises reacting one or more epoxy-terminated polyesters with one or more phosphoric acids. Further provided is an adhesive composition that comprises one or more epoxy phosphate esters, one or more multifunctional isocyanate prepolymers, and one or more multifunctional isocyanate-reactive compounds.

Polyester polyols, processes for making them, and applications for the polyols are disclosed. In some aspects, the polyols comprise recurring units from a thermoplastic polyester or an aromatic polyacid source, a glycol, and a hydroxy-functional ketal acid, ester or amide. Optionally, the polyols incorporate recurring units of a hydrophobe. The polyols are made in one or multiple steps; in some aspects, the thermoplastic polyester or aromatic polyacid source and the glycol are reacted first, followed by reaction with the hydroxy-functional ketal acid, ester or amide. The resulting polyols have good transparency and little or no particulate settling or phase separation. High-recycle-content polyols having desirable properties and attributes for formulating polyurethane products, including aqueous polyurethane dispersions, flexible and rigid foams, coatings, adhesives, sealants, and elastomers can be made. The polyols provide a sustainable alternative to bio- or petrochemical-based polyols.
