The invention provides a polymer having the following general formula :
where
PU is a polymer chain comprising at least one polyurethane chain; and
n 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.
本发明提供了一种具有以下通式的聚合物:
式中
PU 是由至少一条聚
氨酯链组成的聚合物链;以及
n 为 0 至 8;
相同或不同的 X、Y 和 Z 为 H 键位点。
本发明还提供了一种超分子聚合物,该聚合物由彼此形成 H 键的单元组成,其中至少一个单元是根据本发明制成的聚合物。
这种超分子聚合物可用作热熔粘合剂,用于旋转成型或泥浆成型、注塑成型和制造热塑性聚
