| abstract |
The invention provides a polymer having the following general formula (I): where PU is a polymer chain comprising at least one polyurethane chain; andn ranges from 0 to 8;X, Y and Z, identical or different are H-bonding sites. The invention also provides a supramolecular polymer comprising units that form H-bonds with one another, wherein at least one of these units is a polymer according to the invention.The supramolecular polymer is useful as an hot melt adhesive, in rotational or slush molding, in injection molding and in the manufacture of TPU foams. The invention also provides a process for the preparation of the polymer. |
