| 摘 要： | 含氟甲基丙烯酸酯聚合物中的氟原子可使其折光指数n_D很低。这是光导纤维皮材的首要条件。这类材料的大分子主链与作为芯材使用的聚甲基丙烯酸甲酯(PMMA)具有相同的结构,因此其间的相容性和粘结性好,有利于光的全反射;其热稳定性也好,可用于共挤出法制造塑料光导纤维.

| Abstract: | Homopolymers and copolymers of fluoroalkyl methacrylate are the important materials for plastic optical fiber. In this paper the method of the monomer synthesis and the homo- and the copoly-merization condition were reported. Polymers with high molecular weight are obtained by using this method. The theoretically calculated results of the refractive index of the polymers according to the theory of group contribution are in agreement with those of the practical measurements. The Mark-Houwink equationsof the homopolymer are identified by measuring with light scattering and viscosity. |
