Abstract
PURPOSE: To obtain a basic polyamide soluble in organic solvents, e.g. methanol, and water, by polymerizing an α-(N,N-dialkylamino)-ε-caprolactam in the presence of a basic catalyst.
CONSTITUTION: (A) An α-(N,N-dialkylamino)-ε-caprolactam or in combination with (B) a cyclic amid, e.g. ε-caprolactam, of the formula (n is 3W11) is polymerized in the presence of (C) a basic catalyst, preferably metallic lithium, sodium, or potassium, triethylaluminum, or diethylzinc, if necessary (D) a co-catalyst, e.g. N-acetyl-ε-caprolactam. The molar ratio of (A) to (A+B) is ≥0.1, and that of (C+D) to (A+B) is 1:20W500.
USE: Sizes, paper strength improvers, adehesives, and coating materials.
