Abstract: A process for the production of compact, transparent polyisocyanate-polyaddition products by reacting (a) isocyanates with (b) compounds which react with isocyanates, optionally in the presence of catalysts and/or additives etc., in which (b) is a mixture with an average functionality of more than 3 and an average hydroxyl number of 300-950 mg KOH/g. Independent claims are also included for (a) compact, transparent polyisocyanate-polyaddition products obtained by this process; and (b) sun roofs, front, rear and side windows for cars or aircraft, and lamp covers containing these products.
