Abstract: Polyurea elastomers, having a slow rate of cure, and suitable as adhesives or as surface coatings can be prepared by the reaction, in the absence of solvent, of an NCO-terminated quasi-prepolymer with a polyoxyalkylene polyamine and an aromatic diamine chain extender.
The quasi-prepolymers are obtained by reacting polyoxyalkylene polyamine with a stoichiometric excess of aliphatic polyisocyanate.

Abstract: A high selectivity to secondary amines is obtained when nitriles, especially nitriles having 8 to 22 carbon atoms, such as tallow nitrile is passed continuously over a catalyst comprising
   10 to 30 wt.% of cobalt,
   1 to 20 wt.% of copper, and
   1 to 30 wt.% of nickel
in a refractory support of alumina and/or silica.
The reaction can be carried out in two stages, e.g. using the same catalyst for both stages. In the first stage the nitrile is passed over the catalyst with both hydrogen and ammonia. In the second stage, hydrogen is present but ammonia is absent.

Abstract: A useful group of chain extenders for the production of polyurea elastomers by reacting polyisocyanates with amine-terminated polyols are alkyl-substituted piperazines. The preferred piperazines, some of which are novel, are compounds of the formula

wherein R is C₁-C₁₀ alkyl and R′ and R˝ are each alkyl radical or inertly-substituted alkyl. These alkyl-substituted piperazines can be obtained by reacting a 2-amino-2-alkyl-1-alkanol alkylene oxide adduct with ammonia.
