Abstract

"MéTODO DE ESTABILIZAçãO DE COMPOSTOS DE N-OXILOEM COMPOSTOS DE VINILO". Pretende-se impedir a redução aolongo do tempo da quantidade de um composto de N-oxilo emcompostos de vinilo. A redução da quantidade do composto deN-oxilo é suprimida obrigando um composto de N-oxilo, umcomposto de N-hidroxi-2,2,6,6-tetrametilpiperidina e um compostode 2,2,6,6-tetrametilpiperidina a co-existirem em compostos devinilo.
