Method of preparing nontoxic polyamines |
| abstract |
A METHOD OF PREPARING NOVEL POLYETHYLENE POLYAMINES FROM THE REACTION OF AMMONIA AND ETHYLENE DICHLORIDE IS SHOWN. THE PRODUCTS HAVE A HIGH MOLECULAR WEIGHT AND RE PREPARING USING A MOLE RATIO OF AMMONIA TO ETHYLENE DICHLORIDE OF MORE THAN 2,6:1. THE POLYAMINES ARE SUBSTANTIALLY NONTOXIC TO FISH IN CONTRAST TO STANDARD POLYAMINES. |
