Abstract

1 / 2 resumo “processo de polimerizaã‡ãƒo em suspensãƒo de fase reversa para a fabricaã‡ãƒo de grã‚nulos de polã�meros, aparelho adequado para o mesmo, e, grã‚nulos de polã�merosâ€� um processo de polimerizaã§ã£o em suspensã£o de fase reversa para a fabricaã§ã£o de grã¢nulos de polã­meros que compreende formar grã¢nulos de monã´mero aquoso compreendendo uma soluã§ã£o aquosa de monã´meros ou uniã£o de monã´meros solãºveis em ã¡gua etilenicamente insaturados e polimerizar o monã´mero ou uniã£o de monã´meros, para formar grã¢nulos de polã­meros enquanto suspensos em um lã­quido nã£o aquoso, e recuperar os grã¢nulos de polã­meros, em que o processo compreende fornecer em um vaso (1) um volume (2) de lã­quido nã£o aquoso em que o volume de lã­quido nã£o aquoso se estende entre pelo menos um ponto de descarga de grã¢nulo de polã­mero (3) e pelo menos um ponto de alimentaã§ã£o de monã´mero (4), alimentando o monã´mero ou uniã£o de monã´meros aquosos atravã©s dos orifã­cios (5) dentro, ou sobre, do lã­quido nã£o aquoso para formar grã¢nulos de monã´mero aquoso, permitir que os grã¢nulos de monã´mero aquoso fluam para o ponto de descarga de grã¢nulo de polã­mero para iniciar a polimerizaã§ã£o dos grã¢nulos de monã´mero aquoso para formar grã¢nulos polimerizantes, em que os grã¢nulos polimerizantes formam grã¢nulos de polã­meros quando eles atingem o ponto de descarga de grã¢nulo de polã­mero, removendo uma suspensã£o dos grã¢nulos de polã­meros no lã­quido nã£o aquoso do vaso no ponto de descarga de grã¢nulo de polã­mero e recuperar os grã¢nulos de polã­meros solãºveis em ã¡gua ou intumescã­veis em ã¡gua da suspensã£o, em que o monã´mero ou uniã£o de monã´meros aquosos e/ou os orifã­cios sã£o vibrados tal que a frequãªncia multiplicada pelo diã¢metro mã©dio ponderado da gotã­cula esteja entre 150 e 800 mm/s. a invenã§ã£o tambã©m se refere ao aparelho adequado para realizar uma polimerizaã§ã£o em suspensã£o de fase reversa e aos 2 / 2 grã¢nulos de polã­meros obtenã­veis pelo processo ou utilizando o aparelho. alã©m disso, a invenã§ã£o tambã©m se refere aos grã¢nulos de polã­meros tendo um tamanho de partã­cula mã©dio ponderado na faixa de 0,05 a 5 mm que sã£o mantidos em um recipiente em uma quantidade de pelo menos 300 kg tendo um desvio padrã£o de tamanho de partã­cula menor do que 20%. alã©m disso, a invenã§ã£o tambã©m fornece grã¢nulos de polã­meros tendo um tamanho de partã­cula mã©dio ponderado na faixa de 0,05 a 5 mm tendo um desvio padrã£o de tamanho de partã­cula menor do que 20% e tendo uma quantidade de acrilamida residual de menos do que 500 ppm.
