Abstract
Powdered alginate compositions containing polyacrylamide in an amount from about 0.01 to about 0.25 wt. % and having a particle size less than about 300 mesh have enhanced smoothness characteristics, without visible signs of undissolved polymer, upon admixing with water to obtain orally settable, dental impression material.
