Process for the polymerization of allyl ammonium salts and the resulting products

Claim 1

A process for the polymerisation of allyl ammonium salts, wherein a compound corresponding to the following formula ##STR7## in which R 1 and R 2 which may be the same or different and represent hydrogen; an aliphatic, araliphatic or cycloaliphatic radical which may be substituted or R 1 and R 2 may together represent the atoms required to complete a 5- to 7-membered heterocyclic group; R 3 to R 5 which may be the same or different, represent hydrogen or an alkyl radical which may be substituted, A is an anion and/or R 3 represents the radical (--CR.sup.5 R.sup.4 --NR.sup.1 R.sup.2 H).sup.+ A is polymerised in the presence of a phosphorus compound corresponding to the following formula ##STR8## in which R 20 and R 21 which may be the same or different, represent hydrogen; an alkyl group which may be substituted; an aryl group which may be substituted; hydroxyl; alkoxy; aralkyl; aralkoxy; dialkylamino; or R 20 and R 21 represent the group --O--R 23 --O-- where R 23 is an alkyl radical which may be substituted containing no more than 6 carbon atoms, R 22 represents hydrogen; an acyl group which may be substituted; alkyl; dialkylamino; X represents a single electron pair or an oxygen atom, X represents a single electron pair when none of the substituents R 20 to R 22 represents hydrogen.
