- W2079938504 abstract "Abstract Low molar mass (∼ 4000) di‐ and triblock copolymers of styrene and tert‐butyl acrylate were synthesized by atom transfer radical polymerization (ATRP) in bulk and solution conditions. A CuBr/N, N,N′,N″,N″‐pentamethyldiethylenetriamine (PMDETA) catalyst system in conjunction with an alkyl‐halide initiator were used to control the synthesis of the polystyrene macroinitiator and the subsequent copolymerization with tert‐butyl acrylate. Hydrolysis of the tert‐butyl acrylate blocks to acrylic acid blocks in the presence of trifluoroacetic acid resulted in the formation of an amphiphilic block copolymer. Size exclusion chromatography (SEC) and matrix assisted laser desorption ionization ‐ time of flight ‐ mass spectrometry (MALDI‐TOF‐MS) were used to determine the molar mass and molar mass distribution of the polystyrene macroinitiators and the block copolymers. 1 H NMR was used to characterize the polystyrene macroinitiators and the block copolymers, and to confirm hydrolysis of the poly(tert‐butyl acrylate) blocks to poly(acrylic acid)." @default.
