Synchrotron small angle x-ray scattering study of melt crystallized polymers

摘要

In this paper we report a synchrotron small angle X-ray scattering (SAXS) study o f development of structure in semicrystalline Poly(Ether Ehter Ketone), PEEK) and an 80/20 blend with amorphous POly(ether Imide (PEEK/PEI). Samples were treated to dual stage melt crystallization schemem involving initial isothermal crystallization at T_1 followed by a second isothermal period at T_2 (T_1
