六氯环三磷腈基类聚合物的合成

在线状、环状聚磷腈类聚合物的主链结构中磷原子可以与不同的取代基相连接,使此类聚合物材料的物理、化学性质各不相同而表现出性能的多样性.本论文用碳酸钾为质子吸收剂,二氧六环做溶剂,以金属钠、六氯环三磷腈和一缩二乙二醇、二缩三乙二醇为原料,合成出以环状聚磷腈和缩乙二醇类为基本结构单元的二维网状聚合物:一缩二乙二醇缩聚环三磷腈P3N3C l3(OCH2CH2OCH2CH2O)3]n和二缩三乙二醇缩聚环三磷腈P3N3C l3(OCH2CH2OCH2CH2OCH2CH2O)3]n,并对其进行了表征,实验结果表明该类聚合物具有对酸(盐酸、硫酸和硝酸)、碱(氢氧化钠、氢氧化钾)和有机溶剂的耐腐蚀性.

Synthesis of a new type of polymer on hexachlorocyclotriphosphazene

When the phosphorus atoms in polyphosphazenes with chain and ring structures are linked to various substituents the polymers display versatile functions for corresponding changes of the physical and chemical properties.In this paper,the two-dimensional netmork polymers with structural unit of cyclic polyphosphazene and condensed glycol such as poly(triethylene glycol cyclotriphosphazene) and poly(diethylene glycol cyclotriphosphazene) were synthesized from hexachlorocyclotriphosphazene diethylene glycol,triethylene glycol sodium,and sodium carbonate as proton absorber,in 1,4-dioxane solvent.They were characterized by elemental analysis,IR,X-ray diffraction and TGA etc.Experimental results show that above compounds are resistant to acids(hydrochloride acid,sulfuric acid and nitric acid),alkalis(sodium hydroxide,potassium hydroxide) and organic solvents.
