POLYISOCYANATE MIXTURE WHICH IS LIQUID AT TEMPERATURE HIGHER THAN 5 ×C
Polyisocyanate mixts. (I) based on 4,4'-MDI, which are liq. at temps. above 5 degrees C, have (A) a NCO content of 14.5-24 wt.% and (B) an allophanate gp. content of 7.7-14.5 wt.% (calculated as C2HN2O3; mol. wt. = 101). Also claimed is a process for the prodn. of (I) by reacting 4,4'-MDI...

| description | Polyisocyanate mixts. (I) based on 4,4'-MDI, which are liq. at temps. above 5 degrees C, have (A) a NCO content of 14.5-24 wt.% and (B) an allophanate gp. content of 7.7-14.5 wt.% (calculated as C2HN2O3; mol. wt. = 101). Also claimed is a process for the prodn. of (I) by reacting 4,4'-MDI with 4-16C monohydric alcohols at up to 160 degrees C, with a NCO/OH equiv. ratio of (5:1)-(8.5:1), in the presence of a catalyst for allophanate prodn. (II) which is added at the latest after formation of the intermediate urethane. |
