HIGHLY BRANCHED WATER-SOLUBLE POLYAMINE OLIGOMERS, PROCESS FOR THEIR PREPARATION AND APPLICATIONS THEREOF

摘要

The invention relates to a highly branched water-soluble polyamine oligomer (HBPO), a process of preparation and its various applications, in particular, in paper manufacturing.The oligomer of the invention is soluble in water and alcohol, strongly pastes paper materials and confers to paper high water resistance after drying. The use of the oligomer of the invention in the form of aqueous solution makes it a very effective wet-strength additive in the production of cardboard and other packaging materials.
