Abstract
The deformation behavior of semicrystalline polymers associated with polymorphic transformations under tensile deformation is discussed in the case of isotactic polypropylene (iPP). The mechanical properties and polymorphic transformations occurring during plastic deformation of iPP samples with variable stereoregularity, containing only rr stereo-defects, are presented. Thermoplastic materials showing high stiffness, or high flexibility, or elastic properties can be produced depending on the concentration of defects. We report a phase diagram of iPP where the regions of stability of the different polymorphic forms are defined as a function of the degree of stereoregularity and deformation. The values of critical strain corresponding to the structural transformations depend on the stereoregularity that affects the relative stability of the involved polymorphic forms and the state of the entangled amorphous phase. In the case of elastomeric iPP, we show that samples of different stereoregularity present different types of elasticity depending on the degree of crystallinity. The more stereoregular samples, with rr content in the range 7–11% show elastic behavior in spite of the high degree of crystallinity (40–50%). Since elasticity is generally a property of the amorphous phase, probably elasticity in these samples is partially due to the enthalpic contribution associated with the crystallization of the mesomorphic form into the a-form occurring upon releasing the tension. In the case of the less stereoregular sample, with rr content of ≈17%, the degree of crystallinity is very low, and elasticity has essentially entropic origin, as in conventional elastomers.
