Abstract

"método para fabricação de partículas de polímero superabsorvente de cor estável, partículas superabsorventes de cor estável, artigo absorvente, e, fralda". são divulgados polímeros superabsorventes de cor estável possuindo estabilidade de cor a longo prazo e métodos para fabricação dos polímeros. os polímeros superabsorventes são preparados usando um derivado de ácido sulfínico, tal como o ácido 2-hidroxi-2-sulfinatoacético, um sal do mesmo, ou uma mistura do mesmo, como o agente redutor em um sistema iniciador de polimerização para a preparação de um polímero superabsorvente a partir de monômeros. o polímero superabsorvente resultante resiste à degradação da cor durante períodos de armazenagem prolongados, mesmo em temperaturas e umidades elevadas.
