Association behaviors of carbazole-labeled polyacrylamide in

In this work association behaviors of a carbazole-labeled hydrophobically modified polyacrylamide were studied by fluorescence spectroscopy in order to reveal the aggregation-induced spectral features. Both emission and excitation spectra reveal three distinct regimes for the association process of carbazole-labele

We present the synthesis and the characterization of a new class of modified polyacrylamides (MPAM) with the unusual trait of strong emulsification ability, viscosity enhancement capacity, and significant salt tolerance. Besides, the synthesized polymers have the peculiar aggregation behaviors in aqueous solution. The synthesis was carried out by polymerizing the monomers such as acrylamide

Synthesis and characterization of hydrophobically associating

The hydrophobically associating cationic polyacrylamide, one kind of water-soluble hydrophobically associating copolymers, was polymerized by cationic monomer, hydrophobic monomer and acrylamide. As can be imagined, both cationic group and hydrophobic group were incorporated into the polymer molecule chain.

Properties and influence of hydrophobically associating

The properties of hydrophobically associating copolymer P(acrylamide (AM)/2-phenoxylethylacrylate (POEA)), composed of acrylamide and a small amount of POEA (⩽1.0 mol.%) as hydrophobe, were investigated in aqueous solution under various conditions. The results showed that the solution properties were strongly affected by the microstructure of copolymer. The copolymers (BP series) with

reinforcement and behavioral change – organizational behavior

Reinforcement and Behavioral Change – Organizational Behavior

The use of punishment is indeed one of the most controversial issues of behavior change strategies. Although punishment can have positive work outcomes—especially if it is administered in an impersonal way and as soon as possible after the transgression—negative repercussions can also result when employees either resent the action or feel they are being treated unfairly.
