Polyethylene oxide crystallite size

Schonfdd A, Wilke W (1972) Determination of crystallite size and lattice distortion in extended chain polyethylene and their change after oxidative degradation. Kolloid Z. Z. Polym. 250 496... [Pg.110]

Transparency, in general drops with crystallinity (e.g. polyethylene), and with an increase of crystallite size which causes light scattering. Most fillers, colorants and auxiliary additives lead to opacity. Transmittance depends on the refractive index, so that some fillers may preserve full or partial transparency (translucent). There are also dyes that dissolve in the polymer, so that a colored transparent polymer is produced. It is also possible to find stabilizers (including antioxidants or UV absorbers) that do not affect the polymer transparency. Any chemical change in the polymer like degradation or oxidation, or diffusion of some components, may reduce light transmission. [Pg.89]
