从浓乳液合成大分子整体。仅具有聚氨酯网络的基质太软，并且有必要向制剂中添加刚性网络如聚苯乙烯以获得具有良好尺寸稳定性的材料。制备未连接或互连的互穿网络，后者通过使用甲基丙烯酸羟丁酯作为化学连接两个网络的共聚单体。力学性能的修改进行了评价，通过估计的杨氏模量从压缩测试。(c)2005爱思唯尔有限公司保留所有权利。
Macromolecular monoliths were synthesised from concentrated emulsions. Matrixes with only a polyurethane network were too soft and it was necessary to add to the formulation a rigid network such as polystyrene to obtain a material with a good dimensional stability. Either unconnected or interconnected interpenetrating networks were prepared, the later by using hydroxybutyl methacrylate as a comonomer that chemically links both networks. The modifications of the mechanical properties were evaluated by estimating the Young's modulus from compression tests. (c) 2005 Elsevier Ltd. All rights reserved.
