Résumé :

A method utilizing generation of an alkyl iodide (low-mass dormant species) in situ formed in polymerization was adopted to reversible chain transfer catalyzed polymerizations (RTCP) (living radical polymerizations) with several nitrogen and phosphorus catalysts. The polymerization of methyl methacrylate afforded low-polydispersity polymers (Mw/Mn ~1.2–1.4), with Mn values predicted to high conversions; where Mn and Mw are the number- and weight-average molecular weights respectively. This method is robust and would enhance the utility of RTCP.

Résumé :

Abstract An in situ titration of initiator-consuming impurities in amonic polymerizations, using 1,10-phenantroline as an indicator, was developed. The results show that even when impurities are present, it is possible to destroy them prior to the initiation of the polymerization reaction and achieve a better control of molecular weights by adding accurate known quantities of initiator.

Hydrophobic dipeptide crystals recently emerged as novel “organic zeolites” featuring tailorable pore size. In fact, seven out of nine pairwise combinations of L-isoleucine, L-valine and L-alanine amino acids crystallize according to the same charge-assisted hydrogen bond pattern, generating a family of microporous materials with right-handed 1D channels, having diameters in the sub-nanometer domain (<6Å), aliphatic environment and different degrees of helicity.

Polypyrrole (PPy) was chemically prepared via an in situ doped polymerization utilizing seven dopant anions (dopant to monomer molar ratio, D/M = 1/12) to stabilize the positive charges on N of pyrrole rings. These dopant anions were found to play important roles on physical, chemical, and electrical properties of PPy as revealed by several techniques, e.g. X-ray photoelectron spectrometer and the custom-made four-point probe conductivity meter. PPys doped with alpha-naphthalene sulfonate (PPy/A) and beta-naphthalene sulfonate (PPy/B) have good pellet appearance, solubility, thermal stability,
