开发了一种使用复分解聚合物基体的中子屏蔽材料，该基体是热固性树脂。这种屏蔽材料具有可以针对中子吸收剂的不同混合比和针对实验室中的形成进行控制的特性。此外，弹性模量可以在硬化过程中改变，从柔性的弹性体到机械上坚韧的固体。实验在京都大学研究反应堆中进行，以确定这种复分解聚合物屏蔽材料的重要特性，如中子屏蔽性能，二次伽马射线的产生和活化。结果表明，该复分解高分子屏蔽材料与以热塑性树脂为主要成分的其他屏蔽材料一样具有实用性和有效性。(C)2004 Elsevier B.V.保留所有权利。
A neutron shielding material using a metathesis-polymer matrix, which is a thermosetting resin, was developed. This shielding material has characteristics that can be controlled for different mixing ratios of neutron absorbers and for formation in the laboratory. Additionally, the elastic modulus can be changed at the hardening process, from a flexible elastoma to a mechanically tough solid.Experiments were performed at the Kyoto University Research Reactor in order to determine the important characteristics of this metathesis-polymer shielding material, such as neutron shielding performance, secondary gamma-ray generation and activation. The metathesis-polymer shielding material was shown to be practical and as effective as the other available shielding materials, which mainly consist of thermoplastic resin. (C) 2004 Elsevier B.V.
