Research On Polyacrylate Hybrid With Organosilicon And Functional Hybrid With Phthalocyanine

This thesis is divided into two parts. The first part focuses on polyacrylate hybridized with organosilicon. The second part is polyacrylate functionally hybridized with phthalocyanine and its derivatives.In the first part, using polyoxyethylene(10) nonyl phenyl ether (OP-10), and sodium dodecylbenzene sulfonate (SDBS) as emulsifier, and synthesis of styrene (St) /butyl acrylate(BA)/vinyl acetate (VAc)/2-ethylhexylacrylate(2-EHA) tetrapolymer through the emulsion polymerization. Then SDBS was replaced by PVA, and OP-10 to be the low-soap emulsifier. Tetrapolymer was synthesized again, when 5% PVA, the largest polymerization conversion rate, the best stability. A new kind of hybrid emulsion was synthesized by silica sol, TEOS and the tetrapolymer. Infrared spectrum (IR) proved that hydrolytic condensation polymeric reaction happened among PVA, silica sol and TEOS in the organic-inorganic hybrid emulsion. When fixed the content of silica, the ratio between silica sol and TEOS had strong influence on the tensile strength of membrane, when tested by using TEOS: Silica sol was 1:1, the membrane had a maximum tensile strength.In the second part, the copper phthalocyanine (CuPc) reacting with chlorosulfonic acid (HSO3Cl) resulted that -SO2Cl is in the benzene ring, which enhanced reactivity and dissolubility of CuPc. The experiments showed that -SO2Cl group improved its dissolubility. Carbazole/CuPc-SO2Cl was synthesized by reaction between CuPc-SO2Cl and carbazole. Then the values of the nonlinear optical second-order polarizabilities and the ground state permanent dipole moments(βCTμg) was calculated by a non-laser evaluation method-the solvatochromic method. The value ofβCTμg of CuPc/Carbazole compounds was 3.71×10-29μg esu.D, which showed that carbazole/CuPc was a latent second optical compound. Finally, synthesis of styrene (St) / butyl acrylate (BA) /methyl methacrylate (MMA) terpolymer through solution polymerization.and it was functionally hybridized with CuPc, oxotitanium phthalocyanine(TiOPc), and carbazole/CuPc independently. IR could prove that CuPc, TiOPc and carbazole/CuPc had no noticeable change in their structures and polyacrylate would be a potential carrier.
