摘要:
The present invention provides a nanocapsule of a blocked isocyanate encapsulated within a polymeric nanosphere. In one aspect, the polymeric nanosphere is functionalized. Free isocyanate functionality is released upon thermal annealing or UV exposure of the nanospheres containing the blocked isocyanate. This present invention also provides a novel method for encapsulating isocyanates in aqueous media. In one aspect, the method comprises miniemulsion polymerization. The thermally or UV deblocked isocyanate can be used as an active functional group for many potential applications.
摘要:
The present invention is directed to a fatty amide (meth)acrylate monomer, methods of making the monomer, and latex polymers comprising the fatty amide (meth)acrylate monomer. The monomers are derived by reacting unsaturated vegetable oils with ethanolamine or substituted ethanolamine. The vegetable oil derivative is then reacted with either (meth)acryloyl chloride or (meth)acrylic acid to form a fatty amide (meth)acrylate monomer or the product of the reaction of hydroxyethyl (meth)acrylate reacted with isophorone diisocyanate to form a urethane fatty amide (meth)acrylate monomer. The increased hydrophilicity of the fatty amide (meth)acrylate monomer facilitates the diffusion through the aqueous phase. The monomer synthesis is designed to be glycerol ester-free to increase long term stability for monomers and polymers.

Disclosed herein are materials including a polymeric materials such as a coating, a plastic, a laminate, a composite, an elastomer, an adhesive, or a sealant; a surface treatment such as a coating, a textile finish or a wax; a filler for such a polymeric material or a surface treatment, which includes an enzyme such as an esterase (e.g., a lipolytic enzyme, an organophosphorus compound degradation enzyme), wherein the enzyme decontaminates a chemical from the surface of the material. Also disclosed herein are methods of cleaning a surface of a material that comprises an enzyme.
摘要:
Disclosed herein are materials such as a coating, comprising a lipolytic enzyme or organophosphrous compound degrading enzyme. Also disclosed herein are methods of visually detecting enzyme activity in a coating by contacting the coating with a substrate of an enzyme and a visual indicator that changes appearance upon production of a product of enzyme activity on a tack-free coating surface.
摘要:
The present invention provides a soy protein-based adhesive composition and a process for making the composition that may be used in particleboards and similar wood composite systems and that is formed from an aqueous mixture of calcium oxide, pine oil, protein, lignin, and acid. The preferred protein is an enzymatically-modified soy protein and the preferred enzyme is urease.
摘要:
An ethylenically unsaturated vegetable oil is modified by the addition of an enophile or dienophile having an acid, ester or anhydride functionality. The modified vegetable oil is then reacted with a polyethylene glycol (PEG) derivative along with a functional vinyl monomer or a polyethylene glycol derivative that contains a vinyl functionality to form a vegetable oil derivative. The vegetable oil derivative is useful in forming latexes and coatings.

摘要:
A solid isocyanate-based composition having a glass transition temperature of at least 30° C. is produced by at least partially blocking the isocyanate groups of a polyisocyanate with a compound corresponding to the specified Formula I. This blocked isocyanate composition is useful in the production of powder coatings which are capable of being cured at temperatures of from 80 to 220° C.
