Polyacrylamides modifying

Polymin . [BASF AG] Based on polyacrylamide modified polyethylene im-ines letmtion, dewatering, and floccu-... [Pg.289]

In an earlier paper [4], the drag reduction properties of polyacrylamide modified by the incorporation of ionic groups in the main chain were reported. Such a modification enhanced the drag reduction of polyacrylamide to a significant extent. This... [Pg.275]

FIGURE 9.5 UTLC-MALDI-MS spectra of the three proteins myoglobin (a), cytochrome c (b), and lysozyme (c) separated on polyacrylamide modified nonporous silica particles and desorbed/ionized using sinapinic acid as matrix.

Thickener polymers include polyurethanes, polyesters, polyacrylamides, natural polymers, and modified natural polymers [510]. [Pg.11]

A modified acrylamide polymer that is hydrophobically associating has remarkably improved the properties of salt resistance and temperature resistance, compared with high-molecular-weight polyacrylamide [1351]. [Pg.206]

Recently, such a procedure has been used by Wu and Shanks [22] upon a preparation of partially hydrophobized polyacrylamide (PAAm). In this work, the transamidation reaction has been employed to convert amide groups of the parent polymer to the alkylamide groups of the modified PAAm. Scheme 2 shows the reaction chart for the case of the N-isopropylamide derivative. [Pg.108]
