Abstract

A novel C

60-

grafted maleic acid copolymer was prepared using C

 and maleic acid. And then the C

-grafted acid copolymer lead salt additives were prepared using C

-grafted maleic acid copolymer and lead nitrate to modify the burning rates of solid propellants. To obtain the higher content of lead in C

-grafted maleic acid copolymer lead salt

the C

-grafted maleic acid copolymer was coordinated in the presence of lead nitrate. The effect of pH

molar ratio of C

-grafted maleic acid copolymer and lead nitrate

reaction temperature and time on the content of lead in the C

-grafted maleic acid copolymer lead salt were investigated by a singlefactor method. The optimum reaction condition of 5609% lead content in C

-grafted maleic acid copolymer lead salt was obtained in pH = 6.92

molar ratio of C

-grafted maleic acid copolymer and lead nitrate 1:7

reaction temperature 30 ℃

and reaction time 2.0 h. The chemical structures of the C

-grafted maleic acid copolymer lead salt were characterized by FT-IR

UV-vis

GPC

AAS

XRD and XPS analyses. The thermal stability of the C

-grafted maleic acid copolymer lead salt was also investigated by DSC

DTA and TG analyses. Three discrete regions of thermal decomposition were observed in the DTA curve at 275

370 and 462 ℃ respectively. The C

-grafted maleic acid copolymer lead salt had three-steps weight loss

overall weight-loss was 43.6% in the TG curve

which showed good thermal stability.
