PROBLEM TO BE SOLVED: To provide a meta-crosslinked polar benzyl polymer.SOLUTION: A meta-crosslinked polar benzyl polymer is made by combining a transition metal crosslinker, or one or more source compounds capable of reacting to form such a transition metal crosslinker, with a polar benzyl polymer which has been activated for meta crosslinking. In addition, this invention provides a new process for making this meta-crosslinked polar benzyl polymer, comprising a step of combining a transition metal crosslinker, or one or more source compounds capable of reacting to form such a transition metal crosslinker, with a meta activated polar benzyl polymer incompletely crosslinked at its ortho and para positions. |
