Abstract: A process for the preparation of vinylphosphonic acid dichloride and 2-chloroethanephosphonic acid dichloride, wherein 2-chloroethanephosphonic acid derivatives containing 2-chloroethyl ester groups, as produced in the Arbusow rearrangement of tris-chloroethyl phosphite, are heated to 150 DEG to 230 DEG C. in a first stage, and, in a second stage, the residual reaction mixture is reacted with phosgene at 90 DEG -200 DEG C., in the presence of basic catalysts or of alkali metal salts as catalysts, and in the presence of phosphonic acid dichlorides.

Abstract: Process for the preparation of polymers of vinylphosphonic acid in protic diluents with the aid of catalysts which form free radicals, which comprises heating vinylphosphonic acid at temperatures of 40 DEG to 130 DEG C. in a total of 10 to 150% by weight of protic diluents for a total of 4-60 hours in the presence of 1.0 to 5.5% by weight of aliphatic peroxy-esters, diacyl peroxides and/or aliphatic azo compounds which decompose by half in one hour at temperatures below 122 DEG C.
