Abstract

See full text

The present invention relates to a polyisocyanurate plastic obtainable by catalytic trimenzation of a polyisocyanate composition A) which contains oligomeric polyisocyanates and is low in monomeric diisocyanates, where the isocyanurate structure content in the polyisocyanate composition A) is at least 50 mol %, based on the sum total of the oligomeric structures from the group consisting of uretdione, isocyanurate, allophanate, biuret, iminooxadiazinedione and oxadiazinetrione structure that are present in the polyisocyanate composition A). The present invention further relates to a transparent element comprising or consisting of the polyisocyanurate plastic.
