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.

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:
A soy protein based adhesive useful in particleboards and other composites is formed from a mixture of soy protein isolate, a polyol plasticizer and a vegetable oil derivative. The preferred plasticizer is glycerol and the preferred vegetable oil derivative is the maleinized methyl ester of tung oil.
