Synthesis And Study Of Polymer Optical Material

1, Synthesis and optical properties of a new kind of a new type of polyimide with perylene elementN,N-diresorcyl perylene diimide(PTAD) was synthesized byperylene-3,4,9,10-tetracarboxylic acid dianhydride and m-amino phenol with zinc acetate as catalyzer. A new type of polymer with perylene element was prepared by PTAD and TDI.The product own improved solubility and film-forming quality. All the product structure was verified by IR, UV~Vis and elemental analysis.The third-order non-linear optics of the polymer was measured by degenerated four-wave mixing(DFWM) technique and it's coefficient x of the polymer was as high as 1.39X 10"uesu..The Response time of the polymer was 132.59fs . The Fluorescent intensity was measured by Fluorescence Emission Spectrograph and the Fluorescent Intensity was very high.2, The study of ATRP and optical properties of novel functional polymer synthesized byATRPHomogeneous atom transfer radical polymerization of styrene under microwave irradiation(MI) with initiationg system ethyl4-(cWorome%l)berizenecaiboxylate(ECBC)/CuCl/N.N,N.N.N''-pentamemyldie%lenetrianTme(PM DETA) was successfully carried out in cyclohexanone at 76.8癈. Plots of ln[|M]o/[M] vs time showed a linear dependence. A 75.24% conversion for a polymer with number-average molecular weight of 5362 and a polydispersity index (PDI) of 1.455, was obtained under MI (900w) in only 9 min; But 60 min was needed under conventional heating (CH) process to reach a 70% conversion (Mn=5137 and PDI=1.310) at 120, which indicated a significant enhancement of the polymerization rate under MI.We used ethyl 4-chloromethy benzenecarboxylate(ECBC) and 4-chloromethyl benzoic acid(CMBA) to initiate Pst by ATRP method and compared their reactions in different conditions. It's better to polymerize styrene by using CMBA as initiator than by using ECBC as initiator with CuCl/BPY as catalyst. But better polymerization of styrene can be achieved by using ECBC as initiatorthan by using CMBA as initiator with CuCl/PMDETA. The reaction speed is higher in PMDETA/CuCl catalysis system than in BPY/CuCl catalysis system. The coordination of polymer with rare earth metal was confirmed and the optical properties of the polymer were studied. We also used ECBC to manufacture PST-PMA block polymer and coordinated with the compound of rare earth metal after the hydrolysis of the block polymer. The optical properties of the polymer were studied.
