Abstract: The invention relates to a process for the production of elastic, compact or cellular polyurethane-polyurea mouldings in the absence of conventional external mould-release agents in closed moulds by reaction injection moulding, in which a) NCO group-containing prepolymers having NCO contents of from 8 to 20% by weight, prepared by reacting optionally modified diphenylmethane diisocyanates with polyester-polyols (i), polyoxyalkylene-polyols (ii) and/or polyoxyalkylene-polyamines (iii), b) polyoxyalkylene-polyamines containing primary and/or secondary amino groups and having a functionality of from 2 to 8, a molecular weight of from 1000 to 16000 and a content of hydroxyl groups of at most 20% by weight, c) aromatic diamines containing at least one bonded alkyl substituent in the ortho-position to each amino group, d) optionally assistants and/or additives are reacted. f

Abstract: Storage-stable crystallite suspensions which contain a) from 5 to 35% by weight of a polyester prepared from isophthalic acid, terephthalic acid or mixtures of terephthalic acid and aromatic and/or aliphatic dicarboxylic acids, and alcohols having 1 to 6 carbon atoms, having a melt viscosity at 150 DEG C of from 15 to 3000 mPas, as the disperse phase, b) from 65 to 95% by weight of a polyhydroxyl compound having a melting point of below 30 DEG C as the coherent phase, the % by weight data being based on the total weight of components (a) and (b) and c) from 0.2 to 7 parts by weight per 100 parts by weight of the crystallite suspension comprising components (a) and (b), of at least one aliphatic and/or cycloaliphatic amine, alkanolamine and/or product of the reaction of said amines and/or alkanolamines with components (a) and/or (b). The crystallite suspensions are suitable for the preparation of compact or cellular polyurethane plastics or polyisocyanurate plastics containing polyurethane groups, where the polyester (a) of the disperse phase is fully incorporated into the polyurethane skeleton.

Abstract: Diphenylmethane diisocyanate-based liquid polyisocyanate mixtures containing urethane groups and having an isocyanate content of from 12 to 30 percent by weight are obtained by reaction of a polyoxypropylene polyoxyethylene polyol containing 5 to 30 percent by weight of oxyethylene with diphenylmethane diisocyanate-based isocyanates. These polyisocyanate mixtures are storage stable at low temperature and yield flexible polyurethane foams having improved mechanical properties.

Abstract: Asymmetric polyether-polyols having a functionality of from 3 to 8, a hydroxyl number of from 15 to 112 and preferably a compatibility index of less than 50 DEG C are obtained by reacting a) one mol of a polyoxyalkylene glycol having a hydroxyl number of from 15 to 200 with b) from 0.1 to 2 mol of an epoxyalcohol of the formula in which R and R are identical or different and are a hydrogen atom or a -CH2OH radical, x is an integer from 0 to 9 and y is 0 or 1, preferably glycidol, and subsequent c) alkoxylation of the resultant trifunctional to octafunctional intermediate c) in the presence of basic catalysts until the hydroxyl number mentioned has been reached. The asymmetric polyether-polyols are particularly suitable for the production of open-cell polyurethane foams.

Abstract: Heat-hardenable coating compsns., present as aq. dispersions, consist, by wt., of (A) 50-80% water and (B) 20-50% polyesterimide present as particles having dia. =5 mu. (B) contains 0.2-10 wt.% of at least one esterification catalyst. Dispersion has pH 5-9. Used for wire lacquering, insulating metal conductors, esp. wires and rails. Dispersions have good processing ability and storage stability. Gloss and smoothness of stoved lacquers cannot be distinguished from lacquer of same binder applied from soln.

Abstract: Coating, impregnating and bonding agents consisting of suspensions in aqueous solutions of organic polymeric materials of finely divided binders which are insoluble or at the most only slightly swellable in water, which are curable by heat, which are based on polymerizates, polycondensates or polyadducts and which may contain further substances. The suspensions are particularly suitable for coating and impregnation.
