Abstract
Copolymers of aryl phosphonic acids can be made in a bulk polymerization process with unsaturated monomeric hydrocarbons. Preferred are alpha-phenyl vinyl phosphonic acid and styrene. Bulk polymerization process avoids suspending agents, emulsifying agents or water. Absence of halogen avoids environmental problems. A free radical initiator is required.
