Study on the Flame Retardancy of Cellulosic Fiber Treated with Tetrakis Hy droxymethyl Phosphonium Oxalate-Urea
Tetrakis Hydroxymethyl Phosphonium Oxalate-Urea 처리 섬유소섬유의 방염성에 관한 연구
Abstract
The tetrakis hydroxymethyl phosphonium oxalate-urea condensation polymer has phosphonyl group after oxidation and the only three of four primary alcohol groups in THP oxalate react with urea undergoing a crosslinked condensation polymerization. When the THP oxalate-urea polymer is pyrolyzed under atmosphere, phosphorus pentoxide, phosphoric acid or phosphates are formed. On account that phosphorus pentoxide or phosphoric acid formed after being pyrolyzed unnder atmosphere phosphorylates, dehydrates or
