Popis:	The structure of prepolymers (PP) based on polydienediols in bulk and in solution was investigated. It is shown that isocyanate end groups of PP are in an associated state even in fairly dilute solutions. Bonds of different types were determined on a qualitative basis by infrared analysis of crosslinked PP: solution hardening of the PP at room temperature leads to the formation of a network with urea bonds that contains no secondary groups; crosslinking of the PP by means of a diamine at 120°
