Title:
MANUFACTURE OF URETDIONE GROUP-CONTAINING COMPOUND, COMPOUNDTHEREBY AND USE FOR MANUFACTURE OF POLYURETHANE PLASTIC MATERIAL
Document Type and Number:
Japanese Patent JPS6197265
Kind Code:
A
Abstract:
1. A process for the production of compounds containing uretdione groups by at least partial dimerization of the isocyanate groups of organic isocyanates in the presence of compounds containing phosphorus-nitrogen bonds as the dimerization catalysts, characterized in that the reaction is carried out in the presence of 0.1 to 5% by weight, based on organic isocyanate, of H-active organic compounds having a pKs value of at least 6, which contain at least one hydrogen atom attached to oxygen, sulfur or nitrogen, as co-catalyst, organic isocyanates corresponding to the formula see diagramm : EP0178520,P12,F1 in which R is a saturated aliphatic hydrocarbon radical containing 8 to 15 carbon atoms being excluded as the organic isocyanates.
