Summary

Influence of ester group size in polymethacrylates (PMAs), including PMMA, PEMA and PBMA, on β phase crystallization of poly(vinylidene fluoride) (PVF2) in highly oriented films of PVF2 /PMAs=80/20 blends has been investigated by FTIR and TEM. The melt-drawn films of pure PVF2 consist of highly oriented lamellae, in which the α phase is predominant. Adding a given amount of PMAs (20 wt%) into PVF2 results in formation of fibrillar crystals and increase of relative amount of the β phase. The influence extent is in order of PMMA>PEMA>PBMA, regarding the ester group size in the PMAs.
