含磷高分子阻燃剂的研究——磷酸酯高分子的合成(二)
A RESEARCH OF A PHOSPHIDE—BEARING MACROMOLECULES FIRE RETARDANTS——A PROCEDURE OF COMPOSITION OF MACROMOLECULES PHOSPHATES(二)
【摘要】 本文采用磷酸法在PVA分子链上引入磷酸基。而合成磷酸酯高分子阻燃剂,阻燃效果明显,工艺路线短,成本较低,有扩大实验的价值。
【Abstract】 The procedure of Composition of a macromolecules fire retardants of phosphates has been introduced in this paper, It is based on phosphate process, that a phosphono has been introduced into the molecular chain of PVA. This method shows evident property of anti-burn, short flowsheet and low cost. It has more value to engage in enlarge experiment.
