Abstract:

The combination of cellulose and polyurethane is a very promising area of   modern polymer chemistry, as it allows obtaining new materials that combine the positive qualities of both components. Due to insolubility in common solvents, Treating a cellulose surface is a convenient method of its modification. Oligodienes with terminal hydroxyl groups easily converted into macrodiisocyanates with terminal isocyanate groups (MDI) with high reactivity. They give crosslinked polyurethaneurea (PUU) at the treating with polyamines. The PUU preparation on the paper surface by alternately dipping samples into sample diluted benzene or toluene MDI and polyamine (PEPA polyethylenepolyamine and DETA diethylenetriamine) at room temperature. A fast reaction between them leads to the formation of a film on the surface of a paper sample. A significant increase in the strength properties of the certain samples was observed: tensile strength (breaking length), fracture toughness and bursting resistance. A less increase in tear resistance was expressed. The trends remain for both types of paper: an increase in the bursting is of approximately by 2,5 times, break strength by 140–180 %, increase resistance to bursting by 30–60 %, and resistance to tearing by 17–41 % to the value of raw paper. At treating samples with low strengths, their strength increase after treating with PUU approaches 5 times and more.

Keywords: cellulose, polyurethaneurea, polymeric film, dipping process, physical and mechanical paper properties.
