“…These results are consistent with DLS studies performed by other authors, in which two decay modes in diluted HMWSP solutions have also been reported and also associated to the presence of both single chain objects, with or without intramolecular hydrophobic bonds and multichain aggregates. This is in particular the case for Dai et al [25][26][27] working on Hydrophobically modified Alkali Soluble Emulsions (HASE) made of random copolymers of methacrylic acid and ethyl acrylate with 1 mol% of various ethoxylated alkyl hydrophobic monomers, Sato et al [15] working on random copolymers of acrylic acid and N-dodecylmethacrylamide at rather high molar fractions (5 to 30 mol%), Vidal et al [35] working on carboxymethylcellulose modified with 1 to 6 mol% randomly distributed N,N-dihexylamine side-groups and Alami et al [36], working on polyethylene oxyde endcapped with C12 chains. However, to our knowledge, DLS evidence of aggregates in diluted solutions of random HMWSP with SPAM backbones is reported here for the first time.…”

“…Various techniques have been implemented among which viscosimetry [4][5][6][7][8][9][10][11][12], fluorescence [13][14][15][16], transmission, scanning and environmental scanning electron microscopy (TEM, SEM and ESEM) [16][17][18], 19 F NMR spectroscopy [19,20], neutron scattering [21][22][23][24] and Static and Dynamic Light Scattering (SLS and DLS) [14][15][16][25][26][27][28][29][30][31][32][33][34][35][36][37]. Theoretical approaches have also been proposed to describe HMWSP static [38,39] and dynamic [40] properties.…”

“…7). 14,[98][99][100][101][102][103] In semi-dilute solutions, the viscosity increased sharply due to inter-and intra-molecular associations, which rendered them suitable as pH-responsive associative thickeners, and the viscosity enhancement was attributed to the increase in number and strength of active junctions. [104][105][106][107][108][109][110][111] The presence of salt induced the shrinkage of aggregates, while the presence of small amounts of surfactant enhanced the solution viscosity.…”

“…Hydrophobically modified alkali-soluble (HASE) associative polymer has receive increasing attentions in recent years [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. Most of these studies focused on describing the microstructure and the behavior of HASE in the presence of surfactants.…”
