Zusammenfassung:	A method for producing a polyaddition product of isophorone diisocyanate and diols which comprises, reacting a uretidione group-containing dimer of isophoronediisocyanate, which is decomposable by heat into 98% isophorone diisocyanate, with a diol, wherein the ratio of NCO to OH groups is such that the final polyaddition product has free terminal NCO groups, or free terminal OH groups.
