Radiochemical study of the radical copolymerization of styrene and methyl methacrylate
Autor: Bianca M. Gallo, Saverio Russo, Giorgio Bonta, Claudio Uliana
Publikováno v: Polymer. 17:217-220
The rates of initiation for the copolymerization of styrene and methyl methacrylate at 50°, in different reaction media (bulk, acetone, dimethylformamide and dioxane) have been determined by using the isotopic labelling technique (14C - azobisisobut

Ultraviolet Absorption Spectra of Styrene Copolymers. I. Solvent Effects on the Hypochromism of Poly(styrene-co-methyl Methacrylate) at 2695 Å
Autor: Bianca M. Gallo, Saverio Russo
Publikováno v: Journal of Macromolecular Science: Part A - Chemistry. 8:521-531
The use of a UV spectrometer for evaluating the chemical composition of styrene-methyl methacrylate random co-polymers is conditioned by the presence of a marked hypochromism at 2695 A. The composition range where the hypochromic effect appears is st

Some kinetic aspects of radical copolymerization: influence of the reaction medium on the reactivity ratios
Autor: Bianca M. Gallo, Saverio Russo, Giorgio Bonta
Publikováno v: Polymer. 16:429-432
The reactivity ratios for the free radical copolymerization of styrene and methyl methacrylate at 50°C have been evaluated in dioxane, acetone and dimethylformamide solutions. In all these systems there is a marked solvent effect on both r1 and r2,

Chemical reactivity and conformational properties of growing chains. Part 2.—Effect of the reaction medium on the termination kinetics in styrene + methyl methacrylate solution copolymerization
Autor: Saverio Russo, Giorgio Bonta, Bianca M. Gallo
Publikováno v: Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases. 71:1727
The solution copolymerization of styrene and methyl methacrylate in acetone, in dimethylformamide and in dioxan has been interpreted on the basis of a proposed model which includes chain end mobility and chemical reactivity. For all systems the deriv

Chemical reactivity and conformational properties of growing chains. Part 1.—Study on bimolecular radical termination in styrene + methyl methacrylate copolymerization
Autor: Giorgio Bonta, Saverio Russo, Bianca M. Gallo
Publikováno v: Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases. 69:328
The bimolecular termination reaction in free-radical copolymerizations of alkene-type monomers has been studied on the basis of a model which includes both chain end flexibility and chemical reactivity.Two parameters, δAB and δBA, related to the mo
