含烷氧基钕共聚物的合成及其光学性质

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Nd³⁺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。

Syntheses and Optical Properties of Alkoxylneodymium-Containing Copolymers

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 MMAusing AIBNas 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 Nd³⁺) ion characteristic light selective absorbability.So they may be a series of new type optical plastics.
