✦ Synopsis

The presence and behaviour of free radicals in the composite lignin/polypropylene films upon heating were studied by electron spin resonance spectroscopy. The variations of free radical concentration with the proportion of lignin in the composites indicate the radical character of the interaction between paramagnetic sites of the lignin and polypropylene.

The EPR method was used for studying decay of free radicals in a blend of poly(methyl methacrylate) (PMMA) with poly(ethylene oxide) (PEO). The influence of the composition of the blend (up to 70 vol% PEO) and of the time of mixing on the transfer of a radical centre was determined. The time of mixi
