Polyfvinylidene fluoride methacrylate

Likewise, poly (methyl methacrylate) and polyfvinylidene fluoride), the chemical structures of which are shown in Fig. 10.2, make a miscible blend because of the strong specific interactions between the oxygen atoms on the methacrylate and the fluoride group in the vinylidene fluoride group.

Relationship of fatigue crack growth rate per cycle in several polymers as a function of range of stress intensity factor AK, which is a measure of the range in stress concentrated at the crack tip during cyclic deformation (Hertzberg et ai, 1973). PVF, polyfvinylidene fluoride) PMMA, poly(methyl methacrylate) PC, polycarbonate PS, polystyrene.

[PMMA = poly(methyl methacrylate), PVF2 = polyfvinylidene fluoride), PEO = poly(ethylene oxide), PEA = poly(ethylene adipate), PBA = polyfbutylene adipate), PVC = poly(vinyl chloride), PCL = poly(e-caprolactone)].

Figure 11.26 The relationship between AK and fatigue crack growth rates for poly(methyl methacrylate), PMMA polysulfone, PSF polystyrene, PS polyfvinyl chloride), PVC poly(2,6-dimethyl-1,4-phenylene oxide), PPO polycarbonate, PC nylon 66 and polyfvinylidene fluoride), PVp2 (49). Samples with data to the right are more fatigue resistant than on the left, because they require higher levels of stress at the crack tip to propagate the crack.
