Study on the preparation of PU/HBP-NH2 blend film and its properties

The blend films of polyurethane (PU) and amino-terminal hyperbranched polymers (HBP-NH2) were prepared successfully by mixing HBP-NH2 solution and PU. The rate of moisture absorption and mechanical properties were determined. The results showed that the rates of moisture absorption and vapor permeability were improved from 0.34% to 7.51% and from...

Ruthenium(II)-Catalyzed CH Activation with Isocyanates: A Versatile Route to Phthalimides

A cationic ruthenium(II)-complex was utilized in the efficient synthesis of phthalimide derivatives by CH activation with synthetically useful amides. The reaction proceeded through a mechanistically unique insertion of a cycloruthenated species into a CHet multiple bond of isocyanate. The novel method also proved applicable for the synthesis of...

A simple approach for morphology tailoring of alginate particles by manipulation ionic nature of...

A number of different ionic aqueous polyurethane dispersions (PUDs) were synthesized based on NCO-terminated prepolymers. Two different anionic and cationic polyurethane samples were synthesized using dimethylol propionic acid and N-methyldiethanolamine emulsifiers, respectively. Then, proper amounts of PUDs and sodium alginate were mixed to obtain...

Molecular engineering of manipulated alginate-based polyurethanes

The novel soluble alginate-based polyurethanes in organic solvents were synthesized by the reaction of NCO-terminated prepolymers and tributylammonium alginate (TBA-Alg) for the first time. The chemical structures of synthesized polyurethanes were characterized using FTIR, 1H NMR and TGA. The reaction completion was confirmed by disappearing of NCO...
