Abstract
A new betaine-type zwitterionic compound with a long hydrophilic carbon chain,(9-carboxy-nonyl)-dimethyl-[2-methyl-acryloyloxy]-ethyl]-ammonium bromide(CNDMAM),was synthesized from DMand 10-Bromodecanoic Acid.An optimal yield of 78% was achieved when the reaction was carried out withn(DM)∶n(10-Bromodecanoic Acid) =2∶1 at 55℃ for 8 h.The structure of the product was confirmed by1HNMR,FT-IR,titration,and melting point measurement.(9-Carboxy-nonyl)-dimethyl-[2-methyl-acryloy-loxy]-ethyl]-ammonium bromide was copolymerized with AMand the copolymer was characterized by FT-IR.
