Series of polymeric surfactants based on decylacrylate (M1) as hydrophobe and oxypropylated
maleate (Mm2,4,6 and 8 with different molar ratios of propylene oxide) as hydrophiles were
prepared by copolymerization in presence of 1mole% azobiisobutyronitrile (AIBN) as free radical
initiator to afford [PMm2, PMm4, PMm6, and PMm8]a–i. The reaction mixtures were followed
by sulfation and neutralization to attain [PMmS2, PMmS4 PMmS6, and PMmS8]a–i as anionic
copolymeric surfactants, in good yield. These derivatives were purified and characterized by
microanalysis, infrared, and 1
H-NMR spectra studies. Also, surface activity, dispersing properties,
and biodegradability were evaluated. The prepared anionic copolymeric surface active agents
revealed good surface activities and high dispersing properties above 70% special for PMms8d
with 8 mole propylene oxide and equal molar ratio from hydrophilic and hydrophobic monomers.
Also, they are more biodegradable than traditional surfactants |
