The obtained copolymer was esterified with 2-bromoisobutylryl bromide yielding a macroinitiator, poly(methyl methacrylate-co-2-hydroxyethyl methacrylate-co-2-(2-bromoisobutyryloxy)ethyl methacrylate), and its structure was characterized by 1HNMR. This macroinitiator was used for ATRP of styrene to ...
In this paper we report the synthesis, using the “grafting through” method (Scheme 1) and characterization of poly(methyl methacrylate) (PMMA)–silica (diameter ∼20 nm) nanocomposites. To the best of our knowledge this is the first report of grafting polymer to the surface of silica by...
Copolymerization of the cyclic ketene acetal 5,6-benzo-2-methylene-1,3-dioxepane (BMDO) with methyl methacrylate (MMA) is studied with respect to its copolymerization parameters and the suitability to control BMDO/MMA copolymerizations via the reversible addition-fragmentation chain transfer (RAFT)...
The preparation of poly(methyl methacrylate) b polyacrylamide(PMMA b PAAM) using 4,4 azobis[4 cyanopentanoyl( p dimethyl amino) anilide](ACPDA) as an initiator was investigated. At 70 ℃, ACPDA initiated methyl methacrylate(MMA) to give a PMMA prepolymer containing N,N dimethyl anilide term...
of poly(l-trimethylsilylpropyne)(PMSP) based membranes modified by fluorine-con- taining compounds were reported to have very high oxygen permselectivity (a) and perme- ability (P0 ,): one was surface-modified by fluorine gas2 and the other was modified by imbibing hexafluorobutyl methacrylate....
Methyl methacrylate vs Poly(methyl methacrylate): Monomer and polymer May 11, 2024 Methyl methacrylate (MMA) is a monomer unsaturated ester. It has a variety of uses in polymer manufacturing. Surgical applications of methyl methacrylate Nov 7, 2019 Methyl methacrylate monomer, N,N-dimethylp-toluidi...
The swelling of the gel capsule and release of Methyl Orange from the gel capsule were studied. Above the lower critical solution temperature (LCST) of poly(N-isopropylacrylamide) gel, the gel capsule swelled as well as DAA, and the shell layer did not work as a permeability barrier of ...
By adjusting reactant ratio and reactant condition poly (acrylic acid-co-itaconic acid) with different average molecular (2000~10000) and different content of itaconic acid (10% ~ 30%) have been obtained. Dispersing effects of poly (acrylic acid-co-itaconic acid) have been studied through ...
