Polymerization of free secondary amine bearing monomers by RAFT polymerization and other controlled radical techniques

This work describes the polymerization of the free secondary amine bearing monomer 2,2,6,6-tetramethylpiperidin-4-yl methacrylate (TMPMA) by means of different controlled radical polymerization techniques (ATRP, RAFT, NMP). In particular, reversible addition-fragmentation chain transfer (RAFT) polymerization enabled a good control at high conversions and a polydispersity index below 1.3, thereby enabling the preparation of well-defined polymers. Remarkably, the polymerization of the secondary amine bearing methacrylate monomer was not hindered by the presence of the free amine that commonly induces degradation of the RAFT reagent. Subsequent oxidation of the polymer yielded the polyradical poly(2,2,6,6-tetramethylpiperidinyloxy-4-yl methacrylate), which represents a valuable material used in catalysis as well as for modern batteries. The obtained polymers having a molar mass (Mn) of 10,000-20,000 g/mol were used to fabricate well-defined, radical-bearing polymer films by inkjet- printing.

Battery-inspired, nonvolatile, and rewritable memory architecture: A radical polymer-based organic device

A nonvolatile, bistable, and rewritable organic memory device based on radical polymers was prepared and tested. The excellent performance of a battery-inspired memory architecture with a configuration of p- and n-type charge-transporting radical polymers sandwiching a dielectric layer was characterized. The ON-OFF ratio was more than 4 orders of magnitude, and retention and endurance cycles of more than 104 and 103, respectively, were accomplished. Copyright

Strategies for the generation of molecularly imprinted polymeric nitroxide catalysts

(Chemical Equation Presented) Two strategies for preparing catalytically active molecularly imprinted nitroxide-containing polymers are outlined. Both strategies rely upon the thermal rearrangement chemistry of tertiary amine N-oxides. To this end, several polymers were prepared and the polymeric nitroxides were revealed by oxidation with m-CPBA. All of the resulting polymeric catalysts proved to be competent mediators of the oxidation of alcohols.

Phosphites and their production and use

Phosphites represented by the general formula (I): STR1 wherein R1, R2, R4 and R5 independently represent a hydrogen atom, an alkyl group having 1 to 8 carbon atoms, a cycloalkyl group having 5 to 8 carbon atoms, an alkylcycloalkyl group having 6 to 12 carbon atoms, an aralkyl group having 7 to 12 carbon atoms or a phenyl group; R3 and R6 independently represent a hydrogen atom or an alkyl group having 1 to 8 carbon atoms; X1 is a dihydric alcohol residue, wherein HO--X1 --OH defines the corresponding dihydric alcohol from which residue X1, is obtained; and X2 is a direct bond or an alkylene group having 1 to 8 carbon atoms; and the phosphites are useful as stabilizers for organic materials.
