24. Bulk viscosity and its unstable behavior upon storage in polyimide precursor solutions. Tong YJ, Liu TX, Veeramani S, Chung TS. IND. & ENG. CHEM. RES. 41 (17): 4266-4272, 2002.
The bulk viscosity behavior of poly(amic acid) and its amine salt solutions, PAA(ODPA/o-tolidine) and PAS(ODPA/o-tolidine), has been investigated. Both PAA(ODPA/o-tolidine) and PAS(ODPA/o-tolidine) solutions show strong concentration and molecular weight dependence on bulk viscosity, and display critical values on the concentration dependence of bulk viscosity because of increasing the molecular c...

104. ATRP Synthesis of Poly(4-bromostyrene)-b-Poly(propylene glycol) Block Copolymer and Its Self-Assembly in Catalystic Emulsion Polymerization to Form Luminescent Nanospheres with Core-shell Structure. W.Z.Wang*, W.B.Song, R.Wang, T.X.Liu*. J. Polym. Sci. Part A Polym. Chem., 47(5), 1478-1483, 2009.
Poly(propylene glycol)-b-poly(4-bromostyrene) (PPG-b-PBS) block copolymers with
different hydrophobicity have been synthesized by ATRP, which are used as micelle
templates for the synthesis of nanostructured luminescent spheres by catalystic
emulsion polymerizaton. The optical properties of the nanospheres can be tuned by
adding 4,7-dibromo-2,1,3-benzothiadiazole (BTH) in emulsion polymerizati...
