ABSTRACT:
A process for preparing polyvinyl phosphonic acid by the steps of polymerizing bis(2-chloroethyl) vinyl phosphonate in the presence of a free radical initiator or catalyst, such as dicumyl peroxide. The resulting poly bis(2-chloroethyl) vinyl phosphonate is then subjected to acid hydrolysis to obtain high purity polyvinyl phosphonic acid having measurable and controllable molecular weight distribution.
