AB交联共聚物(ABCP)和互穿网络聚合物(IPN)都属交联网状聚合物,只是前者形成一个网络,后者构成两个独立网络(图1),因此两者的性能有明显差别,特别是相容性。目前对ABCP的研究主要是聚酯,聚醚体系,本工作选用便宜的蓖麻油聚氨酯(COPU)和MMA为原料,合成ABCP,得到具有阻尼性能的材料。 AB cross-linked copolymer (ABCP) and interpenetrating network polymer (IPN) are cross-linked network polymer, but the former form a network, the latter constitute two independent networks (Figure 1), so the performance of both obvious Differences, especially compatibility. At present, the research on ABCP is mainly polyester and polyether systems. In this work, we chose COPU and MMA as raw materials to synthesize ABCP and obtain the material with damping properties.
