采用自由基聚合分别合成了红、绿、蓝单色聚合物PMNEu、PMNTb和PMNBe,再根据白平衡原理计算得到三基色配比,按比例共混得到共混型高分子荧光粉,并研究其发光性能及热稳定性。结果表明:当三基色比例为d=6.5∶5.5∶1时,其色坐标为(0.317,0.278),接近正白光(0.33,0.33);在228℃之前,该荧光粉未发生热分解,玻璃化转变温度Tg为134.66℃,较均聚物PMMA提高了29℃左右,有较好的热稳定性。 The red, green and blue monochromatic polymer PMNEu, PMNTb and PMNBe were synthesized by free radical polymerization respectively. Then the three primary colors were calculated according to the principle of white balance. Luminous properties and thermal stability. The results show that when the ratio of three primary colors is d = 6.5: 5.5: 1, the color coordinate is (0.317,0.278) which is close to the positive white light (0.33,0.33) The transition temperature Tg is 134.66 ℃, which is about 29 ℃ higher than that of homopolymer PMMA. It has better thermal stability.
