Abstract: Hard, rigid, non-elastomeric, non-cellular polyurethane compositions manufactured by reacting a liquid hydroxylic polyether having an OH equivalent weight of from 50 to 250, a monofunctional hydroxylic polyether having a molecular weight of from 150 to 10,000 and devoid of further functional groups which react with isocyanates, and an organic polyisocyanate, with or without catalysts, auxiliaries and additives.

Abstract: The invention concerns a process for making heat-resistant polyurethane elastomers from substantially linear polyhydroxyl compounds of high molecular weight, polyisocyanates, chain extenders, and, if desired, catalysts and additives, in which the polyhydroxyl compound is reacted with diisocyanate material in amounts to give an OH:NCO ratio of 1:1.10 to 1:2 and produce an adduct, and the adduct is subsequently reacted with symmetrical aromatic diisocyanate and a diol as chain extender (preferably a linear diol containing 2,4 or 6 carbon atoms) to obtain a crystalline or crystallizable diurethane or polyurethane of good heat resistance.

Abstract: The invention relates to a process for the batch polymerisation of a) vinyl chloride or acrylates having 1 to 10 carbon atoms in the alcohol radical, under conventional conditions of pressure and temperature, in the presence of b) water, c) a saturated or unsaturated fatty acid having 10 to 30 carbon atoms, and d) a water-soluble inorganic initiator, where a reaction batch is first prepared from at least a part amount of components a) and d) and the entire amount of components b) and c) and of ammonium carbamate in the necessary amount, and the polymerisation is then initiated. The PVC polymers prepared in this way are used in particular for the preparation of plastisols.

Abstract: The invention relates to a process for the manufacture of noncellular polyurethane elastomers by reacting 4,4'-diisocyanato-1,2-diphenylethane or diisocyanato-1,2-diphenylethane isomer mixtures with a 4,4'-diisocyanato-1,2-diphenylethane content in excess of 95 percent by weight, higher molecular weight polyhydroxyl compounds and low molecular weight chain extenders optionally in the presence of auxiliaries and additives. The polyurethane elastomers produced in accordance with this invention excel by a greater hardness and improved mechanical properties compared with polyurethane elastomers based on 4,4'-diphenylmethane diisocyanate with otherwise comparable composition.
