Visible Light-Induced Metal Free Surface Initiated Atom Transfer Radical Polymerization of Methyl Methacrylate on SBA-15
Surface initiated atom transfer radical polymerization (SI-ATRP) is one of the most versatile technique to modify the surface properties of material. Recent developed metal free SIATRP makes such technique more widely applicable. Herein photo-induced metal-free SI-ATRP of methacrylates, such as methyl methacrylate, N-isopropanyl acrylamide, and N,Ndimethylaminoethyl methacrylate, on the surface...
متن کاملDispersion polymerization of styrene and methyl methacrylate initiated by macromonomeric azoinitiator
The free radical dispersion polymerization of styrene (St) and methyl methacrylate (MMA) initiated by poly(oxyethylene) (PEO) macroazoinimer (MIM-400) in water/ethanol, was investigated at three different temperatures (50, 60 and 80 8C) for seven polymerization times (3, 6, 9, 12, 24, 36 and 48 h). PStPEO and PMMA-PEO networks were obtained. In each case, polymer gel fractions depend on the pol...
متن کاملPolymerization characteristics of ethyl methacrylate-based resin initiated by TBB.
Polymerization characteristics of 4 types of ethyl methacrylate (EMA)-based resin, composed of EMA and EMA/methyl methacrylate (MMA) copolymers and initiated by tributylborane (TBB), were studied from the aspects of long term changes of residual monomer (RM) and molecular weight (Mw). The resins were polymerized at room temperature for 30 min, stored at 37 degrees C for 24 hr, 1 and 4 weeks and...
متن کاملVisible light-induced polymerization initiated by borate salts of bicationic monochromophoric benzothiazolestyrylium dyes
A series of bicationic monochromophoric hemicyanine dyes based on benzothiazolestyrylium residues were synthesized. The dyeing photoinitiating systems consisting of N-[3-(4-methylpyridino)propyl]-2-(p-substituted styryl)benzothiazolium dihalides as chromophores and n-butyltriphenylborate anion as electron donor were also prepared to achieve an efficient photoinitiators for free-radical polymeri...
متن کاملgradual erasure of subjectivity: a study of samuel beckett’s trilogy in the light of postmodernism
ساموئل بکت بیشتر از هر نویسنده دیگری در نیم? دوم قرن بیستم با گفتارش زمان? ما را به آستان? از هم پاشیدگی کشانده است، آستانه ای که در آن مدرنیته با سرانجام گریزان اما غیرقابل اجتناب خود مواجه می شود. در این تحقیق روی مفهوم فردیت و محو آن در دوران پسامدرن تاکید شده و در طی آن سعی شده است که فردیت مدرن و پسامدرن در رمان های سه گانه بکت بررسی گردد. تحقیق حاضر یک بررسی کتابخانه ای و کیفی بر روی سه ر...
