    • A hard foam formed from a carboxylic acid ester-based polymer having a ring structure, the hard foam being obtained by heating the carboxylic acid ester-based polymer having a ring structure to generate a gaseous organic acid from the carboxylic acid ester-based polymer, and foaming the heated carboxylic acid ester-based polymer with the gaseous organic acid, and a method for producing the same. The hard foam can be used as various heat insulating materials, various vibration isolators, various acoustic materials, various soundproof materials and the like. Therefore, the hard foam is expected to be used for automobile component materials, materials for airplanes, materials for the space field, materials for industries, materials for medical assistance, and the like.
    • 由具有环结构的羧酸酯基聚合物形成的硬质泡沫体,所述硬质泡沫体是通过加热具有环结构的羧酸酯基聚合物从羧酸酯类聚合物产生气体有机酸而得到的, 并用加热的羧酸酯类聚合物与气体有机酸发泡,以及其制备方法。 硬泡沫可以用作各种绝热材料,各种隔振器,各种声学材料,各种隔音材料等。 因此,硬泡沫预期用于汽车部件材料,飞机用材料,空间用材料,工业用材料,医疗辅助用材料等。
