Abstract:

1 Synthesis - The first phase of synthetic research has begun with initial emphasis placed on preparation of copolymers of acrylamide with diacetone acrylamide with diacetone acrylamide AM-DAMM and ampholytic terpolymers of acrylamide and sodium 2-acrylamido-2- methylpropanedimethylammonium chloride with sodium-2-acrylamido-2-methylpropane sulfonate ADASAM series or with sodium-3-acrylamido-3-methyl-butanoate ADABAM series 2 Molecular Characterization - Construction of the proposed preparative scale size exclusion chromatography system is well underway. The system will be able to separate high molecular weight water-soluble polymers for subsequent drag reduction studies and 3 Friction Reduction Measurements - Construction of the proposed tube flow apparatus for measurement of drag reduction is completed. Testing of polyethylene oxide and polyacrylamide standards is in progress. Keywords Bibliographics.
