The instant invention relates to a method for converting phosphorus containing polymers from a two dimensional, layered structure into a three dimensional structure by crosslinking such layers. The method and the resulting crosslinked polymers may be used to encapsulate active materials such as catalysts, pesticides, etc. by intercalating such active materials between the layers prior to crosslinking. Thus, the egress of said active materials into the environment during use may be hindered or prevented. The crosslinking polymers, themselves, may also be used as catalysts or as selective sorbents.
