ABSTRACT:
Network polymers containing phosphorus and nitrogen are deposited and fixed in cellulosic textiles by impregnating the textile with an aqueous solution of an oligomeric vinylphosphonate and a polyethyleneamine or polyethyleneimine and removing water from the impregnated textile to facilitate interaction between the chemical components, thus providing a process and a flame retarding composition for cellulosic textiles.
