Technical Information

Polymerization and Saponification Degrees of GOHSENOL™ Products

GOHSENOL™ products can be roughly categorized into two types; a fully saponified type comprising mostly hydroxyl groups, and a partially saponified type retaining a certain portion of acetic groups.
The relation between the fully saponified type and partially saponified type can be illustrated as below.

Polymerization degree is usually indicated as a viscosity at a particular concentration (usually, 4% at 20℃).

Influence of Polymerization and Saponification Degrees on Properties of GOHSENOL™
The characteristics of GOHSENOL™ products are governed by their polymerization and saponification degrees as summarized below:
Polymerization Degree
Higher Lower
Solution Viscosity Higher Lower
Membrane Strength Greater Weaker
Solubility Less water-soluble More water-soluble
Saponification Degree
Higher Lower
Solution Viscosity Somewhat higher Somewhat lower
Membrane Strength Somewhat stronger Somewhat weaker
Solubility Less soluble in cold water More soluble in cold water
