In addition, photo-set block copolymer and IPN system, with regular microphase domain structure, have higher tensile strength and elongation at break than those of heat-set polymers.

此外，嵌段共聚物和IPN光固化体系形成的相畴结构均一，其抗张强度和伸长率明显高于热固化体系。

An aromatic isocyanate is introduced into an IPN coating system to partly substitute the aliphatic isocyanate.

利用IPN技术将芳香族异氰酸酯引入互穿聚合物网络涂层，取代部分脂肪族异氰酸酯。
