Copolymers for Drag Reduction in Marine Propulsion: New Molecular Structures with Enhanced Effectiveness

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.
