Poly (2-hydroxyethylmethacrylate) membranes for electrochemical use and the manufacture thereof

摘要: The invention relates to a semi-permeable membrane for lead-acid batteries. has microporous structure comprising first polymer and second closely mixed together, the being poly (2-hydroxyethylmethacrylate), known as reticulated HEMA, characterized by fact that comprises one or mixture of several different polymers chosen from among polyoxyethylene glycol, polyvinylpyrrolidone, polyacrylic acid, polymethacrylic copolymers acrylic methacrylic polyacrylates polymethacrylates alkyl, acrylates methacrylates alkyls.
