摘要

正

Fourier transform infrared spectroscopy （FTIR） has been used to study the effect of tacticityof PMMA on β phase formation of poly vinylidene fluoride （PVF

） during quenching process.For pure PVF

quenching at lower temperature results in the formation of β phase crystallites.The critical quenching temperature for β phase formation is about 30℃. Adding a given amountof PMMA （30%） results in the increase of the critical quenching temperature. For the blends ofPVF

with atactic PMMA （a-PMMA）

the critical quenching temperature is about 45℃

whilefor the blends with syndiotactic PMMA （s-PMMA）

attains to about 70℃.
