Polymerization of functionalized diallyl quaternary ammonium salt to poly(ampholyte-electrolyte)

The quaternary ammonium salt, N,N-diallyl-N-carboethoxymethyl-N-carbomethox ypentylammonium chloride 13, on polymerization in aqueous solution using te ut-butylhydroperoxide, afforded the polyelectrolyte 14. The copolymer 15 of the monomer 13 and sulfur dioxide was synthesized in excellent yield. The polyelectrolytes 14 and 15 on acidic hydrolysis gave the poly(ampholyte-ele ctrolytes) 16 and 17 which contain structural features common to both polya mpholytes and conventional polyelectrolytes. The solution properties of the se polymers are discussed in detail. The poly(ampholyte-electrolyte)s, 16 a nd 17 are shown to have considerably higher viscosity than their correspond ing polyelectrolytes 14 and 15. (C) 2000 Elsevier Science Ltd. All rights r eserved.
