Abstract
PURPOSE: The title polymer having a high relative viscosity, readily soluble in cold water, methanol, and chloroform, swelling in benzene, slightly soluble in warm water, consisting of repeating units having a specific structure.
CONSTITUTION: A polymer obtained by polymerizing α-(N,N-dimethylamino)-ε- caprolactam in the presence of an anionic polymerization catalyst, e.g. metallic sodium or potassium, and a co-catalyst, e.g. N-acetyl-ε-caprolactam, at 130W250°C. The polymer has a relative viscosity ≥1.5, preferably 2W5.
USE: Adhesives, sizes, coating materials, paper strength improvers, and resins for printing plates.
