Abstract

Abstract: Fourier transform infrared spectroscopy (FTIR) and transmission electron microscopy (TEM) have been used to study the effect of polymcthaerylates (PMAs),including PMMA,PEMA,PBMA,on the crystalline structure of highly oriented films of poly(vinylidene fluoride) (PVF₂). The melt-drawn films of PVF₂ consist of highly oriented lamellar structure. Addition of PMAs (in 20% by weight) in PVF₂ resulted in the formation of shish-kabab structure and β-phase in order of PMMA>PEMA>PBMA. The results are discussed in terms of the hydrogen bonding between PVF₂ and PMAs.

Key words: polyvinylidene fluoride, polymethacrylate, blend, phase crystal
