摘要

报道了在2MHz和313K的脉冲超声装置下，对聚氯乙烯（PVC）四氢呋喃（THF）溶液的超声吸收、速度、绝热压缩性、弛豫时间和弛豫幅度的测量。结果表明，速度呈线性增加。密度、粘度、吸收系数、弛豫时间和弛豫幅度值随THF中PVC浓度的增加而增加。相反，压缩性随着PVC浓度的增加而降低。这表明PVC和THF分子之间存在相互作用。

Ultrasonic study of molecular association of poly(vinyl chloride) solution in tetrahydrofuran†

Ultrasonic absorption, velocity, adiabatic compressibility, relaxation time and relaxation amplitude measurements are reported on poly(vinyl chloride) (PVC) solution in tetrahydrofuran (THF) using pulsed ultrasonic apparatus operating at 2 MHz and 313 K. Results show a linear increase of velocity. density, viscosity, absorption coefficient, relaxation time and relaxation amplitude values with the increase of PVC concentration in THF. In contrast the compressibility decreases with increasing PVC concentration. This suggests interaction between PVC and THF molecules.
