a new model based on a combination of the polymeric multigrain and multilayer models has been developed to predict the polymerization rate, particle growth, morphology, effective parameters on broadening of the molecular weight distribution, number and weight average of the molecular weight, isotacticity index and bulk density of polymer. mathematical correlations and the kinetics used in this ...

INTRODUCTION A synthetic water-soluble meso-tetra(2,6-dichloro-3-sulfonatophenyl)porphyrinate of iron(III) chloride, Fe-(TDCPPS)Cl, was employed to catalyze the oxidative co-polymerization of penta-halogenated phenols in two humic materials of different origin. MATERIALS AND METHODS Co-polymerization of pentachlorophenol (PCP) was followed by high-performance size-exclusion chromatography (HP...

Enzyme modified electrodes were fabricated with poly(aniline-co-maminophenol). Electrochemical polymerization of aniline and m-aminophenol was performed to get the film of copolymer on the surface of gold electrode. Modified electrodes were fabricated by two methods, physical entrapment and covalent cross-linking. In one of the method, gold nanoparticles were loaded into the copolymer film and ...

Supramolecular polymers are a class of materials characterized by a repetition of monomer units held together by non-covalent forces such as metal coordination, π–π interactions and hydrogen bonding1–4. Compared with their covalent counterparts the unique properties of these polymers have attracted considerable attention, for instance, the self-healing ability that arises from the thermodynamic...

Self-assembly of molecules on surfaces directed by different supramolecular interactions has been widely explored. There are striking examples of molecular surface structures, whose formation is driven by metal co-ordination[1], dipolar coupling[2] or hydrogen bonding[3] interactions. In contrast to these examples, our aim is the formation of covalently linked planar structures by means of poly...
