New quaternary ammonium salts

The invention comprises compounds of the formula: CH2 = C(R)-CONH-R1-N(tert.)X wherein R is hydrogen or a methyl group, R1 is an alkylene radical, N (tert.) represents the group of atoms forming an aliphatic, cycloaliphatic, araliphatic or heterocyclic tertiary amine in which the nitrogen atom may carry as a substituent a carboxyalkyl group, and X represents the monovalent anion of a salt-forming acid. X is exemplified by bromide, chloride, phosphate, acetate, stearate, methosulphate, dodecosulphate and para-toluenesulphonate anions. The compounds are prepared by quaternizing an N-(tertiary amino-substituted alkyl)-acrylamide or methacrylamide with, for example, alkyl, alkenyl or aralkyl halides, alkyl sulphates, or halogen substituted fatty carboxylic acid salts, if desired in presence of a polymerization inhibitor such as 2 : 4-dimethyl-6-tert.-butylphenol. Specified amide starting materials are N-(b - diethylaminoethyl) - methacrylamide, N-(g - dimethylaminopropyl) - methacrylamide, N-(g - diethylaminopropyl) - methacrylamide, N-(g - dibutylaminopropyl) - methacrylamide, N-(b - piperidinoethyl) - methacrylamide, N - (b -dimethylaminoethyl) - acrylamide, N - (b - diethylaminoethyl) - acrylamide, N - (g - dimethylaminopropyl) - acrylamide, N - (g - dibutylaminopropyl) - acrylamide, N - (b - dimethylaminoethyl) - methacrylamide, N - (b -morpholinoethyl) - methacrylamide, N - (g -piperidionopropyl) - methacrylamide and N-(g - hexamethyleneiminopropyl) - methacrylamide. The examples describe the preparation of trimethyl - (b - methacrylylaminoethyl) - ammonium methosulphate, methyl - (b - methacrylylaminoethyl) - piperidinium methosulphate, diethyl - methyl - (b - methacrylylaminoethyl) - ammonium methosulphate, trimethyl-(g - methacrylylaminopropyl) - ammonium methosulphate, methyl - diethyl - (g - methacrylylaminopropyl) - ammonium methosulphate, trimethyl - (b - acrylaminoethyl) - ammonium methosulphate, methyl - diethyl(b - acrylylaminoethyl) - ammonium methosulphate, trimethyl - (g - acrylylaminopropyl) - ammonium - methosulphate, allyl - diethyl - (b -methacrylylaminoethyl) - ammonium bromide, methyl - diethyl - (g - methacrylylaminopropyl)-ammonium - para - toluenesulphonate, butyldiethyl - (g - methacrylylaminopropyl) - ammonium bromide, diethyl - benzyl - (g - meth-,-acrylylaminopropyl) - ammonium chloride methyl - dibutyl - (g - methacrylaminopropyl)-ammonium methosulphate, methyl-dibutyl-(g -acrylylaminopropyl) - ammonium methosulphate, tributyl -
