The N2-molecule-aryl-cation pair formed as the first intermediate in dediazoniations of arenediazonium ions can be trapped with CO in H 2 0 with formation of the corresponding arenecarboxylic acids. This reaction is considered as a model for the reverse of dediazoniation, since CO is isoelectronic w
The fluorescence of labelled poly(acrylic acid) (PAA\*) is used to study the kinetics of the complexation between PAA\* and polyvinylpyrrolidone (PVP) both in the presence and in the absence of Cu 2+ ions. It is found that the fluorescence intensity of the anilino-naphthalene sulphonic residues atta
## Abstract The pH effect on microsphere formation in the dispersion copolymerization of methyl methacrylate with vinylbenzylβterminated poly(acrylic acid) (PAA) macromonomers is studied. The diameter of poly(methyl methacrylate) (PMMA) microspheres is minimum around pH = 8. Dynamic light scatterin
