摘　　要：本文用Bridgman多项式,Tait方程和Murnaghan方程描述了聚异戊二烯在室温下2GPa压力范围内的等温压缩行为,Tait方程和Murnaghan方程成功地拟合了聚异戊二烯的等温P-V数据。Bridgman polynomial, Tait and Murnaghan equation of state have been used to describe isothermal compression of polyisoprene up to 2GPa. Tait and Murnaghan equation are very accurately for multisegmentally fitting the isothermal P-V data of polyisoprene with the universal values CT = 0.0894 for Tait and CM=0.1016 for Murnaghan. The possible secondary transitions of polyisoprene on pressure are also presented.
