Abstract
"COMPOSIçãO ESTABILIZADA CONTRA POLIMERIZAçãOPREMATURA, PROCESSO PARA INIBIR A POLIMERIZAçãOPREMATURA DE OLEFINAS LEVES REATIVAS, E, USO DEUMA FENILENODIAMINA E DE UM NITRóXIDO". O assunto dainvenção é uma composição estabilizada contra polimerizaçãoprematura compreendendo: a) um monómero de olefina leve e umaquantidade inibidora de polimerização eficaz de b) pelo menos umafenilenodiamina de fórmula (1) em que R~ 1~, R~ 2~ e R~ 3~ sãoiguais ou diferentes e são hidrogênio, alquila de cadeia reta ouramificada de 1 a 20 átomos de carbono, alquila de cadeia reta ouramificada de 1 a 20 átomos de carbono, que é substituída por uma três grupos arila, arila de 1 a 12 átomos de carbono ou arila de 1a 12 átomos de carbono que é substituída por um a três gruposalquila de 1 a 6 átomos de carbono; e c) pelo menos um nitróxidode fórmula (II) em que R^ 4^ e R^ 5^ são independentementealquila de 1 a 4 átomos de carbono ou são juntos pentametileno; eZ~ 1~ e Z~ 2~ são cada um metila ou Z~ 1~ e Z~ 2~ juntosformam uma metade de ligação que pode ou não conterheteroátomos ou grupos carbonila e que, adicionalmente, podemser substituídas por hidróxi, cianoidrinal, amino, alcóxi, amido, cetal,carbóxi, hidantoína, carbamato ou um grupo uretano. Um outroassunto da invenção e um processo para inibir a polimerizaçãoprematura das olefinas leves e o uso de uma fenilenodiamina juntocom pelo menos um nitróxido, para impedir a polimerização dasolefinas leves reativas.
