Notes:
The microstructure of semicrystalline polymers solidified with and without concurrent applied strain is reviewed. Fluid flow in the filling and packing stages of injection-molding are discussed. Observations of the microstructures of a number of polymers under various conditions are described. In general, the microstructure is extremely inhomogeneous and anisotropic; a skin layer is highly oriented (or, in some cases, finely granular), whereas the core is composed of larger, isotropic spherulites. The principles governing the formation of such microstructures are given. Relations between microstructure and macroscopic properties are briefly described.
