  • Patent number: 6683151
    Abstract: The invention relates to a compound comprising a reaction product of (A) an isocyanate functional compound of which at least 40 wt. %, relative to the total amount of (A), has a molecular weight of at least about 500, and (B) a nitrogen-containing compound capable of reacting with said isocyanate functional compound (A). The reaction product has a molecular weight of less then about 20,000 and comprises an effective amount of groups that are able to form reversible intermolecular physical interactions such that a resulting compound shows polymeric mechanical properties at a temperature below a transition temperature. The nitrogen-containing compound is, for instance, melamine, urea, acetoguanamine, benzoguanamine, cyanamide, dicyanamide, thiourea, isocytosine, pyrimidone or aminopyridine. The supramolecular compound comprising a suitable amount of the reaction products exhibits a relatively high elongation at break.
