摘要 用三烷氧基钕与顺丁烯二酸酐反应合成10种与MMA有良好相容性的含烷氧基钕单体,将其与MMA共聚制得10种含烷氧基钕共聚物。研究了共聚物材料的光学性质及其影响因素。表明含烷氧基钕共聚物较PMMA有较高透光率和折光率,折光率随钕含量增加而线性增大,且具有Nd ̄(3+)离子特征的光选择吸收性,是一类性能优异的新型光学塑料。 For increasing in the transmittancy of rare earth metal-containing polymer,ten alkoxylneodymium-containing monomers, which have good compatibility with MMA,are synthesized by the reactions of neodymium alkoxides with maleic anhydride. Then ten alkoxylneodymium-containing copolymers are prepared by the copolymerizatons of these monomers with MMA using AIBN as an initiator. Studies on optical properties of these copolymers indicate that, in comparison with PMMA, alkoxylneodymium-containing copolymers have higher transmittancy and refractive indexes,and their refractive indexes increase linearly with increasing Nd content. Moreover, they have Nd ̄(3+) ion characteristic light selective absorbability. So they may be a series of new type optical plastics.
