Abstract
Novel polystyrene grafted polyolefin compositions having a high level of grafting are made using a novel process which involves suspending styrene in water. The polystyrene grafted polyolefin compositions can then be converted into ion exchange membranes that are particularly useful in electrolytic cells.
