Abstract

Patente de Invenção: <B>"AGENTES SUPRESSORES DE CRESCIMENTO, COMPOSIçõES CONTENDO-OS E MéTODO DE USO EM PROCESSOS DE POLIMERIZAçãO"<D>. A invenção refere-se a agentes de crescimento que compreendem um produto de condensação entre um aldeído, um composto de fenol e um ácido carboxílico aromático, substituído por hidróxi no núcleo aromático. Os produtos são particularmente eficazes na redução ou supressão de formação de crescimento na polimerização de cloreto de vinila ou acetato de vinila, outras substâncias copolimerizáveis estando opcionalmente presentes. Outros objetivos da invenção são as composições contendo os agentes acima, seus empregos como agentes de crescimento, métodos para suas preparações e os produtos obtidos deles, os processos de polimerização realizados em reatores cujas paredes internas são revestidas com estes agentes e os polímeros obtidos destes processos.
