Amphiphilic copolymers of sodium 2-acrylamido-2-methylpropanesulfonate (AMPS) and dodecylmethacrylamide (DodMAAm) were synthesized. The ratio of the reduced viscosities of these copolymers in water and in 0.2 mol/L NaCl solution shows that these copolymers containing from 50 to 66 mol % of DodMAAm h

Abstract
Ethylene copolymers containing even small amounts of certain Nβalkylacrylamides show some unusual properties: transparency while semicrystalline, preservation of stiffiness during reduction in crystallinity, and an unusual melt flowβversusβsolution viscosity relationship. These properties are due to hydrogen bonding between macromolecules. By proper choice of the Nβalkyl group, copolymers containing more than 95% ethylene were made which were stiff, tough, and transparent.
