Controlled Polymerization of N-trimethylsilyl Methacrylamide: A New Polymethacrylamide Precursor

N-Trimethylsilyl amines for controlled ring-opening polymerization of amino acid N-carboxyanhydrides and facile end group functionalization of polypeptides.

We report a new strategy that uses N-trimethylsilyl (N-TMS) amine to mediate controlled ring-opening polymerization of amino acid N-carboxyanhydrides (NCAs). This polymerization proceeds via a unique, trimethylsilyl carbamate (TMS-CBM) propagating group that results from the cleavage of the Si-N bond of N-TMS amine followed by NCA ring opening. Propagation of the polypeptide chains proceeds thr...

A new precursor for preparation of magnetite (Fe3O4) nanoparticles

An anionic Fe(II) complex, (BMIM)4[Fe(CN)6] (where BMIM is 1-butyl-3-methylimidazolium), was synthesized in ionic liquid [BMIM][PF6] under reflux condition. The complex was characterized by elemental analysis and spectroscopic methods. The magnetite (Fe3O4) nanoparticles were prepared by the hydrothermal and solvothermal (in ionic liquid [BMIM][PF6]) methods from (BMIM)4[Fe(CN)6] as a precursor...

A New Approach for Monte Carlo Simulation of RAFT Polymerization

In this work, based on experimental observations and exact theoretical predictions, the kinetic scheme of RAFT polymerization is extended to a wider range of reactions such as irreversible intermediate radical terminations and reversible transfer reactions. The reactions which have been labeled as kinetic scheme are the more probable existing reactions as the theoretical point of view. The ...

A new family of (A, N)-implications: Construction and properties

This paper deals with a new family of (A, N)-implications that derived from fuzzy negation and continuous monotone function, and some properties, like the left neutrally, the exchange principle, the ordering property and the laws of contraposition, of the proposed family of (A, N)-implications are studied. Moreover, the T-conditionality and the Modus tollens for the new family of (A, N)-i...
