Abstract:
Reaction product obtained by reacting(A) an isocyanate functional compound which is the reaction product between (i) an isocyanate, and (ii) a compound containing at least one functional group selected from the group consisting of hydroxy, acid, and amino functional groups, at least 40% by weight of said compound (ii) having a weight average molecular weight of at least about 450, and (B) a nitrogen-containing compound that reacts with said isocyanate functional compound (A), wherein, said reaction product has a number average molecular weight less than about 20,000 and, wherein said reaction product comprises groups which form reversible intermolecular physical interactions comprising at least hydrogen bonding with other of said reaction product from the same or different isocyanate functional compound (A) and nitrogen-containing compound (B), such that the compound resulting from such reversible physical attractions exhibits a tensile strength of at least about 0.05 mPa at a temperature below a transition temperature and has an elongation at break at 25Â° C. of at least about 2%.
