An AB monomer, useful for the production of condensation polymers, wherein the AB monomer has the structure: A&#x2014;X&#x2014;C&#x2014;Y&#x2014;B; wherein A is a carboxylic acid or ester or reactive carbonyl derivative, Y is a bisanhydrohexitol unit derived from isosorbide, isoidide or isomannide; X is selected from the group consisting of aromatic rings, substituted or unsubstituted heterocycles, and saturated or unsaturated aliphatic chains; and B is OH and C is an ester carbonyl link with the carbon attached to X and the oxygen attached to Y, and wherein the AB monomer is at least about 98% pure endo-substituted bisanhydrohexitol derivative or an at least about 98% pure exo-substituted bisanhydrohexitol derivative.

Polyesters from assymetrical monomers based upon bisanhydrohexitols

Isosorbide-derived epoxies and methods of making same are disclosed. Isosorbide and its isomers are attached to glycidyl ether to make crosslinkable epoxy resin monomers. Adding the hydrophobic functional group into the backbone of isosorbide epoxy or adjusting the amount and type of crosslinker is operable to modify the mechanical properties and water uptake ratio (from &#x3c;1 wt % to &#x3e;50 wt %) of the isosorbide-derived epoxies for different uses. High water uptake epoxies with controllable biodegradation rate are suitable for drug delivery systems or extracellular matrices for biomedical applications, while low water uptake epoxies with strong mechanical properties may be used for can coatings, bone cements and other industrial additives and adhesives.

Isosorbide-derived epoxy resins and methods of making same

A process for producing copolymers of a polymer and asymmetrically substituted compounds of bisanhydrohexitols, including the bisanhydrohexitol isosorbide. In a specific example, the AB monomer isosorbide 2-(4-carbomethoxybenzoate) is synthesized and copolymerized with polyester to form a copolyester. The asymmetrically substituted compounds provide a way of incorporating bisanydrohexitols that may be derived from natural sources into polymers.

Polyesters from asymetrical monomers based upon bisanhydrohexitols

A process for producing a copolyester through the production of an AB monomer of isoidide - Isodide 2-(4-carbomethoxyphenyl) ether. In certain aspects, the AB monomer is produced by performing the steps of: protecting the 2-position of isosorbide with a protecting group; functionalizing the 5-position of isosorbide with a suitable leaving group to form a reactive ester; nucleophilicly displacing the leaving group in a reaction with an alkali metal alkoxide or phenoxide to give an isoidide ether through a stereochemical inversion of the 5-position; and removing the protective moiety to create the AB monomer. In certain embodiments, the copolyester is produced by melting the AB monomer and a polyester, optionally with a catalyst.

Polyester ethers derived from asymmetrical monomers based upon bisanydrohexitols

Disclosed is a method for preparing polyoxazolidones wherein an ether of a bisanhydrohexitol is reacted with a diisocyanate under conditions which form polyoxazolidones. Preferred bisanhydrohexitols include isoidide, isomannide and isosorbide. The polyoxazolidones are highly crosslinked, rigid, and have high solvent resistance.

Polyoxazolidones derived from bisanhydrohexitols

The present invention relates to foam compositions which are expanded with hydrohalocarbon blowing agents in the presence of additives which decrease the formation of haloalkenes during the polymerization. Thus, the present invention provides compositions comprising polyisocyanate, polyol, hydrohalocarbon blowing agent, catalyst, surfactant, and at least one additive wherein the additive is capable of decreasing the amount of decomposition of said dehydrohalocarbon blowing agent to haloalkenes during polymerization of the polyisocyanate and the polyol. Depending upon the polyol and polyisocyanate used and the quantity of polyisocyanate used, the compositions may be used in pour-in-place molded foams; rigid urethane spray foams; rigid high and low density foams for slabstock, froth foams, and molded foams; rigid laminated boardstock; or specialty foams.
