Synthesis and characterization of hydrophobically modified
Hydrophobically modified polyacrylamide (PAM) polymers were synthesized by means of an aqueous micellar copolymerization, the di-alkyl substituted acrylamides di-n-propylacrylamide (DPAM) and di-n-octylacrylamide (DOAM) being used as hydrophobic comonomers.The number of hydrophobic blocks was varied using three different comonomer contents (f=1, 3 and 5 wt.%).

Hydrophobically Modified Dimethylacrylamide Synthesis
The synthesis and rheological behavior of hydrophobically modified copolymers based upon N,N‘-dimethylacrylamide (DMAM) containing dodecyl or octadecyl groups are described. The polymers were synthesized by free radical copolymerization in homogeneous solutions of toluene. This synthesis method ensured that the hydrophobic groups were incorporated individually into the copolymer, i.e., in a

The water-soluble hydrophobically modified polyacrylamide (HMPAM) has been extensively investigated in the last thirty years. Research interest stems mainly from two areas: solu-tions and hydrogels. Interest in HMPAM solutions has arisen primarily from controlling viscosity at different shear rates (rheology) in many technologies.

When Microrheology, Bulk Rheology, and Microfluidics Meet
In this work, we present new insights related to a debate on the morphological structure of hydroxyethyl cellulose (HEC) molecules when dissolved in water, i.e., whether HEC adopts a linear-flexible or a rod-like fibrillar configuration. We have employed “seven” rheological techniques to explore the viscoelastic properties of HEC solutions at different time and length scales.
