This micrograph is a good control for study of a multiphase polymer containing carbon black. A TEM micrograph of a black, polyurethane filled polyacetal is shown in Fig. 5.64B. Interestingly, the carbon black particles have enhanced the image contrast as they are located within the dispersed polyurethane, and thus the dispersed phase can be observed without staining. [Pg.230]

Multiphase polymers containing polyurethane are common toughened polymers in which it has long been known that phase separation is important in determining structure-property relation-... [Pg.345]

It should be emphasized that the molecular theories presented in this chapter are valid only for flexible homopolymers and thus they cannot describe the rheological behavior of stmctured polymer systems, including multicomponent and/or multiphase polymers, such as block copolymers, liquid-crystalline polymers, thermoplastic polyurethanes, immiscible polymer blends, highly filled polymers, and nanocomposites. We discuss this subject in the remaining chapters of this volume. [Pg.143]

In segmented polyurethanes as well as in many other block copolymers incompatible polymer segments are combined. This incompatibility of different CRUs means that block copolymers often form multiphase systems (see TEM-... [Pg.252]
