| description | The present invention relates to novel polyisocyanurate plastics which are obtainable by catalytic trimerization of a polyisocyanate composition A) which contains oligomeric polyisocyanates and is low in monomeric diisocyanates. "Low in monomeric diisocyanates" means that the polyisocyanate composition A) has a content of monomeric diisocyanates of at most 20% by weight. The invention further relates to the use of these polyisocyanurate plastics for production of coatings, films, semi-finished products and mouldings, and to a process for producing polyisocyanurate plastics comprising the following steps: (a) providing a polyisocyanate composition A) which contains oligomeric polyisocyanates and is low in monomeric diisocyanates, "low in monomeric diisocyanates" meaning that the polyisocyanate composition A) has a content of monomeric diisocyanates of at most 20% by weight; (b) catalytically trimerizing the polyisocyanate composition A).
La présente invention concerne de nouvelles matières plastiques à base de polyisocyanurate qui peuvent être obtenues par trimérisation catalytique d'une composition de polyisocyanate A) qui contient des polyisocyanates oligomères et qui a une faible teneur en diisocyanates monomères. « À faible teneur en diisocyanates monomères » signifie que la composition de polyisocyanate A) a une teneur en diisocyanates monomères d'au plus 20 % en poids. L'invention concerne en outre l'utilisation de ces matières plastiques à base de polyisocyanurate pour la production de revêtements, de films, de produits semi-finis et de pièces moulées, et un procédé de production de matières plastiques à base de polyisocyanurate comprenant les étapes suivantes : (a) fourniture d'une composition de polyisocyanate A) qui contient des polyisocyanates oligomères et qui est à faible teneur en diisocyanates monomères, « à faible teneur en diisocyanates monomères » signifiant que la composition de polyisocyanate A) a une teneur en diisocyanates monomères d'au plus 20 % en poids ; (b) trimérisation catalytique de la composition de polyisocyanate A). |
