【発明の名称】イソシアヌレート基含有ポリイソシアネートの製造方法
Document Type and Number:
Japanese Patent JP2832473
Kind Code:
B2
Abstract:
A novel process for the preparation of modified, isocyanurate-containing polyisocyanates containing aliphatically and/or cycloaliphatically bonded isocyanate groups involves the chemical modification of some of the isocyanate groups of organic diisocyanates using aliphatically and/or cycloaliphatically bonded isocyanate groups in the presence of a quaternary ammonium or phosphonium fluoride as catalyst and in the presence of carbon dioxide passed into the reaction mixture. If desired after blocking using blocking agents for isocyanate groups, the modified polyisocyanates obtainable in this way can be used as the isocyanate component in polyurethane paints.
