WET STRENGTH RESINS

WET STRENGTH RESINS Disclosed are novel wet strength resins for paper. The resins are produced by reacting an epihalohydrin, such as epichlorohydrin, with an aminopolyamide-polyureylene intermediate derived by reacting methylbisaminopropylamine with oxalic acid or a diester of oxalic acid and with urea.

Terpolymers of diallylamine

LINEAR TERPOLYMERS OF A DIALLYLAMINE, SULFUR DIOXIDE AND ACRYLAMIDE OR A LOWER ALKYL SUBSTITUTED ACRYLAMIDE ARE DESCRIBED. THE TERPOLYMERS ARE PRODUCED BY CYCLOPOLYMERIZING A SALT OF THE APPROPRIATE DIALLYLAMINE IN THE PRESENCE OF SULFUR DIOXIDE AND THE AMIDE USING A FREE RADICAL CATALYST. THE TERPOLYMERS ARE USEFUL AS TREATING AGENTS FOR PAPER AND TEXTILES AND AS INTERMEDIATES FOR THE FORMATION OF DERIVATIVES WHICH ARE THE RESINOUS REACTION PRODUCTS OF THE TERPOLYMER WITH AN EPIHALOHYDRIN OR AN ALDEHYDE.

Reaction products of epihalohydrin and polymers of diallylamine and their use in paper

WATER-SOLUBLE, ALKALINE CURING RESINS WHICH ARE THE REACTION PRODUCTS OF AN EPIHALOHYDRIN AND A POLYMER OF A DIALLYLAMINE ARE DISCLOSED. THE RESINS ARE PARTICULARLY USEFUL AS WET STRENGTH AGENTS FOR PAPER AND ADDITIONALLY GIVE SUPERIOR DRY STRENGTH TO PAPER.
