Popis:	The kinetics of urethane and gel formation was studied in compositions with various contents of monofunctional molecules of the copolymer of THF with propylene oxide and of the branching agent. The critical parameters of gel formation were calculated, respecting the reactivity differences between the components. The considerable difference between the calculated and experimental values is explained by the processes of micro- and macrocyclization in the system.
