Abstract

"PROCESSO PARA POLIMERIZAR ETILENO". Um método para polimerizar etileno e, opcionalmente, outros monómeros em um reator de alta pressão, em pressões de 1000 - 4000 bares e temperaturas entre 140 e 320<198>C, em temperaturas e pressões quando a água comporta-se de uma maneira supercrítica. De acordo com o método inventivo, água é introduzida dentro do reator em uma maneira contínua e intermitente.
