  Polyurethane-urea elastomers are made using as a chain extender 2-methyl-1,3-propanediol-bis-p-aminobenzoate which is the reduction product from hydrogenating 2-methyl-1,3-propanediol-bis-p-nitrobenzoate. The latter composition is preferably made by esterifying p-nitrobenzoic acid and 2-methyl-1,3-propanediol using a stoichiometric excess of the diol initially, adequate to render the reaction mixture processible, and after converting to a nonvolatile form sufficient diol to form diester with substantially all of the acid, removing free diol by distillation while continuing the esterification of unreacted acid and transesterification of monoester formed to diester. This process, which can be applied broadly to esterification of other nitroaromatic acids with other aliphatic diols, produces high yields of diester without needing extraneous solvent for processibility and with only water as a by-product. The 2-methyl-1,3-propanediol-bis-p-aminobenzoate exhibits reactivity and processing characteristics which make it a suitable drop-in replacement for MoCA in polyurethane-urea elastomer manufacture.

  聚氨酯-脲弹性体是使用2-甲基-1,3-丙二醇双对氨基苯甲酸酯作为链延长剂制成的，该酯是从氢化2-甲基-1,3-丙二醇双对硝基苯甲酸酯还原产物中得到的。最好的方法是使用过量的二元醇与对硝基苯甲酸和2-甲基-1,3-丙二醇酯化反应，使反应混合物可加工，并转化为非挥发形式，足够的二元醇与几乎所有酸形成二酯，通过蒸馏去除游离的二元醇，同时继续酯化未反应的酸和单酯形成的酯交换反应。这个过程可以广泛应用于其他硝基芳香酸与其他脂肪二元醇的酯化反应，产生高收率的二酯，无需外加溶剂以便加工，并且只产生水作为副产物。2-甲基-1,3-丙二醇双对氨基苯甲酸酯表现出的反应性和加工特性使其成为聚氨酯-脲弹性体制造中适用于MoCA的直接替代品。

  A prepreg comprises the following elements [A], [B] and [C]: [A]: reinforcing fibers; [B]: a resin composition including a thermosetting resin and a thermoplastics resin which is soluble in the thermosetting resin, which resin composition is capable of forming a micro-phase separation structure; and [C]: fine particles which are insoluble in the element [B] and which do not contain an elastomer component; the element [C] being localized in a surface region of the prepreg. A composite prepared from the prepreg has high impact resistance, high interlayer toughness and high tensile strength.
