Abstract
The preparation of diethyl 4-vinylbenzylphosphonate by an Arbuzov reaction of triethyl phosphate, followed by dealkylation and formation of an amine salt of dicyclohexylamine is described. This salt was homopolymerized and was also copolymerized with methyl methacrylate. The polymers exhibited a glass transition temperature close to 200 deg. C. Cross-linking was attributed to formation of phosphonic anhydride type linkages. It is concluded that these phosphorus-containing materials may find uses as flame-retardant materials, anticorrosive coatings, adhesion promoters, etc. 24 refs.
