Abstract:
1. A process for the preparation of a supramolecular polymer comprising about 1-50 4H-units, the process comprising reacting a 4H building block comprising a reactive group with a prepolymer and a chain extender in a reaction mixture comprising less than 10 wt. % of a non-reactive organic solvent, based on the total weight of the reaction mixture, wherein the 4H building block is formulated as a liquid at a temperature lower than about 100° C. and comprises a 4H-unit and a reactive group according to Formula (I): wherein 4H represents a 4H-unit; L represents a polymeric group having a molecular weight between 500 and 5000 Da; F r is 1-4; the prepolymer is an isocyanate functional polyol; and the chain extender has the Formula (II): wherein n=2 to 5; Z is a C G represents —OH and/or —NH
