Abstract
NEW MATERIAL:An aliphatic triisocyanate I (n is integer of ≥ 4).
EXAMPLE: 1,6,11-Undecatriisocyanate.
USE: A raw material for polymers, e.g. coatings, films, foams, elastomers, adhesives, fibers, etc., Excellent in light stability, weather resistance and solvent resistance. Coating film prepared from the compound has excellent quick-drying characteristics, surface hardness, etc.
PREPARATION: The compound I is prepared by (1) decarboxylating and dimerizing an aliphatic lactam, an α,ω-aminocarboxylic acid or their polymer in the presence of a strong base, (2) converting the resulted amino shiff base II or diaminoketon III to a triamine IV by the catalytic reduction with hydrogen in the presence of ammonia, and (3) reacting the triamine IV with phosgene. The compound II and III are in equilibrium in the presence of water.
