Summary
Alternating copolymers of poly(phenylvinyl alkyl thioethers) and maleic anhydride covalently labeled with 2,2,6,6-tetramethyl-4-hydroxypiperidine-1-oxyl and 2,2,6,6-tetramethyl-4-aminopiperidine-1-oxyl free radicals in different solvents were investigated. The alkyl groups were Me, Et, sec-Bu and n-Bu. The rotational correlation times, τ R, characterizing the rate of rotation of spin label, are not significantly affected by the alkyl group at low solvent concentration. However, at higher dilution (above Tg) τ R is increasing with the increased bulkiness of the alkyl group. The motion of the two spin labels attached to the copolymer segment through different chemical linkage and an implication on the effective correlation time was discussed.
