P. Favresse et al., Synthesis and free radical copolymerisation of new zwitterionic monomers: amphiphilic carbobetaines based on isobutylene, EUR POLYM J, 37(5), 2001, pp. 877-885
Several new, hydrolytically stable ammonioacetate and pyridiniocarboxylate
monomers were synthesised varying the length of hydrophobic side chains and
the nature of the zwitterionic moiety. The synthetic strategy chosen avoid
s the presence of residual salt in the betaines, thus making them well suit
ed for model studies. The monomers bearing long alkyl spacers between the p
olymerisable group and the zwitterionic moiety exhibit surfactant propertie
s ("surfmers"). The monomers do not undergo free radical homopolymerisation
, but are suited for copolymerisation with a number of different monomers.
Copolymers of monomers with long alkyl spacers tend to form superstructures
