Abstract

We investigate the effect of hydrophobic aggregation in alkali-swellable acrylic thickener solutions on shear and extensional flow properties at technically relevant polymer concentrations using the commercial thickener Sterocoll FD as model system. Apparent molecular weight of aggregates in water is M w  ≈ 108 g/mol and decreases by more than an order of magnitude in ethanol. Zero shear viscosity η 0 is low and shear thinning is weak compared to the high molecular weight of the aggregates. Linear viscoelastic relaxation is described by the Zimm theory up to frequencies of 104 rad/s, demonstrating that no entanglements are present in these solutions. This is further supported by the concentration dependence of η 0 and is attributed to strong association within the aggregates. Extensional flow behavior is characterized using the capillary break-up extensional rheometry technique including high-speed imaging. Solutions with ϕ ≥ 1% undergo uniform deformation and show pronounced strain hardening up to large Hencky strains. Elongational relaxation times are more than one order of magnitude lower than the longest shear relaxation times, suggesting that aggregates cannot withstand strong flows and do not contribute to the elongational viscosity.

This can be estimated by the so-called Bond number Bo = ρgD(t)2/4σ (see, e.g. , Anna and McKinely 2001) with the acceleration of gravity g, Bo < 0.2 for a filament diameter of 1.5 mm, σ = 35 mN/m, and ρ = 1,000 kg/m3.

It should be noted that the low σ value even for the pure aqueous solution is due to the presence of surfactants from the emulsion polymerization process.
