Abstract: The invention relates to a process for the preparation of mixtures of diphenylmethane diisocyanates and polyphenylpolymethylene polyisocyanates (crude MDI) having a reduced iodine colour value by reaction of corresponding mixtures of diphenylmethanediamines and polyphenylpolymethylenepolyamines with phosgene in the presence of at least one inert organic solvent at elevated temperature, in which, after phosgenation of the reaction mixture is complete, low-molecular-weight alkanols, polyhydric alcohols, preferably di- to octahydric alcohols having a molecular weight of 60 to 350, or mixtures thereof are incorporated in an effective amount, advantageously in an amount of 0.01 to 5% by weight, relative to the crude MDI weight, the phosgene and the inert organic solvent are then separated off, 0 to 5% by weight, relative to the crude MDI weight, of at least one phenol-based antioxidant and/or aryl phosphite are added to the reaction product, and the reaction mixture is subjected to a heat treatment.

Abstract: Mixt (I) of diphenylmethane di-isocyanates and polyphenylpolymethylene polyisocyanates is pred by, (1) reacting corresp mixt of diphenylmethane diamines and polyphenylpolymethylene polyamines with phosgene (II) in presence of at least one inert organic solvent at raised temp, (2) after phosgenation has finished, incorporating effective amt of phosphite (III) which is a tri-and/or di-alkyl phosphite, (3) removing excess (II) and solvent, and (4) heating reaction mixt. USE/ADVANTAGE - For use in prodn of compact or foamed polyisocyanate polyaddn prods, partic flexible semihard or hard foams contg urethane and opt isocyanurate gps, having lighter colour. (I) having reduced iodine colour is obtd without addn of small proportion of water after phosgenation but before complete sepn of (II) (US4465639), which promotes corrosive effect of C12, HCl and (II) on appts and causes risk of leak of (II) or (II)-contg reaction mixt.

Abstract: Mixtures of diphenylmethane diisocyanates and polyphenylpolymethylene polyisocyanates (crude MDI) having a reduced iodine color number are prepared by reacting the corresponding mixtures of diphenylmethanediamines and polyphenylpolymethylene-polyamines with phosgene in the presence of one or more inert organic solvents at elevated temperatures by a process in which low molecular weight alkanols, polyhydric alcohols, preferably dihydric to octahydric alcohols having a molecular weight of from 60 to 350, or mixtures thereof are incorporated in an effective amount, advantageously in an amount of from 0.01 to 5% by weight, based on the weight of crude MDI, into the reaction mixture after the end of the phosgenation, the phosgene and the inert organic solvent are then separated off, from 0 to 5% by weight, based on the weight of crude MDI, of one or more phenol-based antioxidants and/or aryl phosphite are added to the reaction product, and the reaction mixture is subjected to a thermal treatment.

Adhesive composition contains up to 99.9 wt.% prepolymer (I) with urethane groups and a urea content of 0.05-1 wt.% (calculated as NH-CO-NH), 0.1-20 wt.% fibrous filler, 0-20 wt.% usual additives and 0-10 wt.% activator. (I) is derived from component A containing (A1) diol(s) and/or polyol(s), (A2) organic compound(s) containing primary and/or secondary amino groups and/or water and optionally (A3) other compound(s) with functional groups capable of an addition reaction with isocyanate groups and component B containing compound(s) with polyisocyanate groups.
