  In a process where an ortho-alkylnitrobenzene derivative and a vinyl compound as starting materials are used to prepare a 1,5-diaminonaphthalene derivative via a 4-(2-nitrobenzene)propane derivative and a 5-nitro-1-tetralone derivative, the ortho-alkylnitrobenzene derivative and a vinyl compound having an electron withdrawing group such as an acrylonitrile derivative and an acrylate may be reacted in the presence of a base to provide an aromatic nitro compound. An aromatic nitro compound such as 4-(2-nitrobenzene)butanonitrile thus obtained may be cyclized to safely, cost-effectively and selectively provide a 5-nitro-1-tetralone derivative without forming any isomer. Furthermore, from the 5-nitro-1-tetralone derivative, a 1,5-diaminonaphthalene derivative may be prepared without forming any isomer.

  在一个过程中，使用邻位烷基硝基苯衍生物和乙烯化合物作为起始原料，通过4-(2-硝基苯基)丙烷衍生物和5-硝基-1-四氢萘酮衍生物制备1,5-二氨基萘衍生物，邻位烷基硝基苯衍生物和带有电子吸引基团的乙烯化合物，如丙烯腈衍生物和丙烯酸酯，可以在碱的存在下发生反应，以提供芳香硝基化合物。因此，所得的芳香硝基化合物，如4-(2-硝基苯基)丁酮腈，可以环化，安全、经济高效地选择性地提供5-硝基-1-四氢萘酮衍生物，而不形成任何异构体。此外，从5-硝基-1-四氢萘酮衍生物中，可以制备1,5-二氨基萘衍生物，而不形成任何异构体。

  The use of certain prepolymers of 4,4'-methyienebis-(phenyl isocyanate), in place of the latter diisocyanate itself in the preparation of polyurethane-polyureas using aromatic diamine extenders, has a number of advantages par- ticuiariy when the compositions are prepared by reaction injection molding techniques using two streams of reactants. The principal advantages are (i) a useful increase in gel time and (ii) a ratio of amounts of the two reactant streams which more nearly approaches 1:1. This latter factor not only improves the efficiency of mixing of the components in the mixing head but, together with the longer gel time, significantly increases the output of mixed reactants per unit of time. The prepolymers of 4,4'- methyienebis(phenyi isocyanate) employed to achieve the above results are those derived from polyoxy-ethylene polyoxypropylene polyether diols and triols (MW = 1000-10.000), polytetramethylene glycols (MW = 600-5.000) and polyester diols and triols (MW = 500-8.000).

  在使用芳香族二胺扩展剂制备聚氨酯聚脲时，使用 4,4'-亚甲基双（苯基异氰酸酯）的某些预聚物来代替后者的二异氰酸酯本身，具有许多优点，尤其是在使用两股反应物流通过反应注射成型技术制备组合物时。主要优点有：(i) 有效延长凝胶时间；(ii) 两股反应物的比例更接近 1:1。 后一个因素不仅提高了混合头中各组分的混合效率，而且与更长的凝胶时间一起，显著提高了单位时间内混合反应物的产量。为达到上述效果而使用的 4,4'-亚甲基双（苯基异氰酸酯）预聚物是从聚氧乙烯聚氧丙烯聚醚二醇和三醇（分子量＝1000-10.000）、聚四甲基二醇（分子量＝600-5.000）和聚酯二醇和三醇（分子量＝500-8.000）中提取的。

  Polyamide-polyurea containing polymers are disclosed that are derived from the reaction of (A) an organic polyisocyanate: (B) an organic compound having at least two active hydrogen containing groups; and (C) from 15 to 160 parts per 100 parts of said (B) of a chain extender combination comprising (i) a particular enamine and (ii) an aromatic diamine and optionally (iii) an extender diol wherein the ratio of equivalents of (A) to total equivalents of (B) and (C) is within the range of from 0.90:1 to 1.10:1. The polymers find particular utility in the preparation of RIM parts having excellent physical properties. At the same time, the polymers are characterized by slower gel times than prior art aromatic diamine extended polymers thereby allowing the filling of larger molded parts.
