    摘要： There is provided a resin composition for producing a composite part, comprising: a) from 30 to 90 wt % by weight of the composition of an epoxy resin component; and b) from 5 to 50 wt % by weight of the composition of a curative component; wherein the epoxy resin component comprises N,N,N′,N′-tetraglycidyl-4,4′-diamino-3,3′-dimethyldiphenylmethane (M-TGDDM) in an amount of at least 30 wt % by weight of the epoxy resin component; and further wherein the curative component comprises one or more of a diaminodiphenyl sulfone, a diaminobenzophenone, a fluorene diamine, a methylene bis aniline, including hybrid methylene bis anilines, or a substituted diamine toluene. There is also provided the use of N,N,N′,N′-tetraglycidyl-4,4′-diamino-3,3′-dimethyldiphenylmethane (M-TGDDM) as a compression performance improving additive in a resin composition for producing a composite part. There are also provided curable composite components, cured composite components produced therefrom and the use of such components as aircraft components.

    摘要： The invention relates to polymeric cobalt bearing compounds, in particular for use as metal-rubber adhesion promoters (RAPs) in tires, belts and hoses. Known active substances are a.o. cobalt stearates, naphthenates, resinates, decanoates, boro-decanoates and many other forms of acylates. While these substances appear to enhance the metal-rubber adhesion, all of them also come with significant drawbacks, a.o. linked to the relatively high bioavailability of cobalt in these substances. The invention concerns more particularly a polymer comprising Co-carboxylate sequences, with a Co content of at least 3% by weight, and with a mean molecular weight of more than 2000. Several synthesis methods, allowing to reach relatively high Co concentrations in the polymer, illustrate the invention. The invented polymers show a strongly reduced bioavailability of Co compared to currently available products, as demonstrated by aqueous leaching tests. As RAPs, they perform similarly to commercial products, as shown by pullout tests.

    摘要翻译： 本发明涉及聚合钴载体化合物，特别是用作轮胎，带和软管中的金属橡胶粘合促进剂（RAP）。 已知的活性物质是a.o. 硬脂酸钴，环烷酸盐，树脂酸盐，癸酸盐，硼酸癸酯和许多其它形式的酰化物。 虽然这些物质似乎增强了金属 - 橡胶的附着力，但它们都具有显着的缺点。 与这些物质中钴的相对高的生物利用度有关。 本发明更具体地涉及包含Co-羧酸酯序列的聚合物，Co含量为至少3重量％，平均分子量大于2000.几种合成方法允许在聚合物中达到较高的Co浓度 说明本发明。 与目前可获得的产品相比，本发明的聚合物显示出强烈降低的Co的生物利用度，如通过含水浸出试验所证实的。 作为RAP，它们与商业产品类似，如拉出测试所示。
