摘要
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。
COPU/PMMA crosslinked copolymer (ABCP) was synthesized from vinyl-terminated castor oil prepolymer and MMA. The Mc densities, dynamic mechanical properties and morphologies of the ABCPs with defferent composition were studied. The results show that COPU/PMMA ABCP is a semicompatible system and has potential application for damping material.
