A functional aspartate prepared by A) reacting an aziridine with a Michael-acceptor molecule to form an aziridinyl aspartate, and B) reacting the aziridinyl aspartate with an active hydrogen containing compound to form the functional aspartate. The functional aspartate can be used in adhesive, sealant or coating compositions that also include an isocyanate functional material. The composition can be used in a method of bonding a first substrate to a second substrate that includes applying a coating of the above-identified adhesive composition to at least one surface of the first substrate or the second substrate, and contacting a surface of the first substrate with a surface of the second substrate, where at least on of the contacting surfaces has the coating applied thereto. The composition can also be used to coat substrates.

Aspartic ester functional compounds

A method of irreversibly immobilizing an enzyme in a polyurethane and an enzyme-containing polyurethane having a degree of immobilization of the enzyme of approximately 100%. The synthesis of waterborne polyurethanes in the presence of enzyme has enabled the irreversible attachment of the enzyme to the polymeric matrix. The distribution of immobilized enzyme as well as activity retention are homogeneous within the polyurethane. Decreasing ECC hydrophobicity, via the use of a less hydrophobic polyisocyanate prepolymer during polymerization, significantly enhanced the intrinsic activity of the ECC.

Irreversible immobilization of enzymes into polyurethane coatings

The present invention relates to novel polyaspartimides, their method of production and the use of these polyaspartimides as reactive components for polyisocyanates in two-component polyurethane coating compositions. The polyaspartimides are prepared by reacting a polyether amine with a maleimide.

Moisture-curable, polyether urethanes with reactive silane groups and their use as sealants, adhesives and coatings

The present invention relates to a polyether urethane containing one reactive silane group and one or more polyether segments having a number average molecular weight of 1000 to 15,000, wherein the reactive silane groups are incorporated by the reaction of an isocyanate group with a compound corresponding to the formulawherein

Polyether urethanes containing one reactive silane group and their use in moisture-curable polyether urethanes

The present invention relates to novel aspartates, their method of production and the use of these mono and polyaspartates as reactive components for polyisocyanates in two-component polyurethane coating compositions and for preparing polyurethane prepolymers.

Process for preparing aspartates

The invention relates to a process for reducing the monomeric aziridine content in a polyaziridine forming reaction mixture by adding to the polyaziridine forming reaction mixture an excess of a carbodiimide scavenger wherein the excess is based on the equivalent ratio of scavenger to monomeric aziridine, and to a product obtained by this process and to a coating composition containing the product obtained by the process.

Reduction of monomer content and stabilization of polyaziridines

The invention relates to a process for reducing the monomeric aziridine content in a polyaziridine forming reaction mixture by adding to the polyaziridine forming reaction mixture an excess of an organic carbonate scavenger wherein the excess is based on the equivalent ratio of scavenger to monomeric aziridine, and to a product obtained by this process and to a coating composition containing the product obtained by the process.

The present invention relates to novel aspartates, their method of production and the use of these aspartates as reactive components for polyisocyanates in two-component polyurethane coating compositions and for preparing polyurethane prepolymers. The aspartates are prepared by first reacting a di- or polyamine with an unsaturated ester and then reacting the resultant product with a maleimide.

This invention provides a method of irreversibly immobilizing an enzyme into polyurethane coatings. This invention also provides for an enzyme-containing coating having a degree of immobilization of the enzyme of approximately 100%. The synthesis of waterborne polyurethane coatings in the presence of enzyme has enabled the irreversible attachment of the enzyme to the polymeric matrix. The distribution of immobilized enzyme as well as activity retention are homogeneous within the coating.
