Cationically active water soluble polyamides

TLDR: In this paper, the use of these agents as DRAINAGE AIDS, RETENTION AGENTS, and FLOTATION AGENTS in CONNECTION with RELATIVELY THICK PAPER or CARDBOARD MANUFACTURE is also discussed.

Abstract: NOVEL CATIONICALLY ACTIVE, WATER SOLUBLE POLYAMIDES OBTAINED BY THE ALKYLATION WITH A BIFUNCTIONAL ALKYLATION AGENT UNTIL THE ALKYLATION AGENT IS USED UP, OF A REACTION PRODUCT RESULTING FROM THE REACTION OF A DICARBOXYLIC ACID OR A FUNCTIONAL DERIVATIVE THEREOF WITH A POLYALKYLENEPOLYAMINE ARE PRODUCED, EXEMPLIFIED ALKYLATION AGENTS HAVING THE FORMULA CL-CH2-CH(-OH)-CH2-N(+)(-CH3)2-CH2-CH(-OH)-CH2-N(+)(-CH3)2 -CH2-CH(-OH)-CH2-CL 2CL(-) CL-CH2-CH(-OH)-CH2-N(+)(-CH3)2-CH2-CH2-N(+)(-CH3)2-CH2- CH(-OH)-CH2-CL 2CL(-) EXEMPLIFIED REACTION PRODUCTS OF A DICARBOXYLIC ACID WITH A POLYALKYLENEPOLYAMINE BEING THE REACTION PRODUCTS OF DIETHYLENETRIAMINE WITH ADIPIC ACID, OF DIETHYLENETRIAMINE AND TRIETHYLENETETRAMINE WITH ADIPIC ACID, OF BIS-(3AMINOPROPYL)-AMINE WITH ADIPIC ACID AND N,N''-BIS-(3AMINOPROPYL)-1,4-DIAMINO-BUTANE WITH ADIPIC ACID DIMETHYL ESTER; THE USE OF THESE EXEMPLIFIED CATIONICALLY ACTIVE, WATER SOLUBLE POLYAMIDES AS DRAINAGE AIDS, RETENTION AGENTS AND FLOTATION AGENTS IN CONNECTION WITH RELATIVELY THICK PAPER OR CARDBOARD MANUFACTURE IS ALSO EXEMPLIFIED.
