“…Several authors discussed the polymerization behavior of DADMAC, for which a monomer exponent of 2 or 2.9 was reported, but partly controversially [65,66,67]. They considered viscosity effects, monomer association ,and change of the ionic strength differently.…”

“…They considered viscosity effects, monomer association ,and change of the ionic strength differently. Topchiev et al proposed k t to decrease with increasing density and viscosity of the polymerization medium when the initial monomer concentration increased [65]. Others hypothesized the formation of monomer hydrophobic associates as well as reduced repulsive electrostatic forces between the positively charged growing radical and the cationic monomer molecules to cause an increase of k p [66,67].…”

Abstract:The free-radical homopolymerization of 1,3-bis(N,N,N-trimethylammonium)-2-propylmethacrylate dichloride (di-M) and 1,3-bis(N,N,N-trimethylammonium)-2-propylacrylate dichloride (di-A) in aqueous solution yields cationic polyelectrolytes (PEL) with theoretical/structural charge spacing of only «0.12 nm. The high charge density causes condensation of «82% of the chloride counterions. The high level of counterion condensation reduces the ionic strength in the polymerizing batch when the monomer molecules connect to PEL chains. This has the consequence that the hydrodynamic and excluded volume of the PEL molecules will change. Studies of the free radical polymerization revealed non-ideal polymerization kinetics already at low conversion and additionally autoacceleration above a certain monomer concentration and conversion. Similar autoacceleration was not observed for monomers yielding PEL with charge spacing of 0.25 or 0.5 nm. Coulomb interactions, monomer association, steric effects, and specific features of the monomer constitution have been evaluated concerning their contributions to the concentration dependence and conversion dependence of kinetic parameters. The different backbone constitutions of di-M and di-A not only influence the polymerization kinetics but also equip poly(di-M) with higher hydrolytic stability. The experimental results confirm the impact of electrochemical parameters and the necessity to reconsider their inclusion in kinetic models.

“…Nitrogen-containing synthetic polyelectrolytes of a diallyl nature can be used as coagulants, flocculants, soil builders, as well as for the purification of clear (drinking) and wastewater [1][2][3]. Therefore, chemical science discovered new tasks to expand the range of diallyl polyelectrolytes that would have a whole variety of valuable properties, including those with controlled hydrophilichydrophobic and acid-base properties, and the presence of biological activity, which is an urgent problem.…”

The resulting monomer is N,N-diallylaminoethanoic acid and a polymer based on it. The structure of the monomer and polymer is confirmed by physicochemical methods. The toxic properties of poly-N,N-diallylaminoethanoic acid were investigated on the Drosophila melanogaster test system. The results obtained allow us to conclude that poly-N,N-diallylaminoethanoic acid in concentrations of 1 % does not have a toxic effect.
