A STUDY ON COPOLYMERIZATION OF GRADIENT REFRACTIVE INDEX ROD PREPARED FROM DIALLYL PHTHALATE-METHYL METHACRYLATE COPOLYMER
邻苯二甲酸二烯丙酯和甲基丙烯酸甲酯共聚物梯度折射率棒制备过程的研究

GRIN rods of DAP-MMA copolymer with long diameter and high difference of refractive index have been prepared by diffusion copolymerization. Conditions of copolymerization are studied. The reason that cracks are brought about is given. The optimum condition in the fabrication of the rods has been found.
