Makromoleküle: Band 2: Physikalische Strukturen und Eigenschaften

Längst ein Klassiker: Kein anderes deutschsprachiges Werk über Makromoleküle erscheint bereits in der sechsten Auflage! Mit Band 2 liegt nun eine zeitgemäße Behandlung der phsikalischen Eigenschaften von Makromolekülen vor. Er schildert in seinem ersten Teil die Struktur isolierter Moleküle und die zur Strukturaufklärung verwendeten Verfahren, bevor dann Mikro- und Makrokonformationen von Makromolekülen beschrieben werden.

XRD, AFM, TEM, and UV–vis spectroscopy studies show that the dispersion of clay is best in the Ch/MEK solvent combination and hence polymer– filler interaction is also the highest. TEM images shown in Fig. 14a, b clearly elucidate the aforementioned phenomena. 50 MPa, respectively) for the Ch/MEK system due to the minimum difference in interaction parameter of HNBR–solvent (wAB) and sepiolite–solvent (wCD). Choudhury et al. have also studied the effect of different nanoclays [NA, 30B, 15A, and sepiolite (SP)] and nanosilica (Aerosil 300) on the mechanical properties of HNBR [36].

The reinforcement ability of the gels depends on their crosslinking densities. Guth– Gold and Kerner particulate composite reinforcement models have been used to understand the reinforcement behavior of these nanogels [149]. 3 Dynamic Mechanical Analysis Dynamic mechanical analysis (DMA) measures the response of a viscoelastic material to a cyclic or sinusoidal deformation as a function of the temperature. , the E00 /E0 (or G00 /G0 ) ratio, which indicates the occurrence of molecular mobility and segmental transitions such as the glass transition temperature (Tg) [150].

7c). The NA clay platelets are aligned in the molding/flow direction. In all the HRTEM images, well distributed individual NA clay platelets can be seen easily, along with a few intercalated clay layers consisting of a few clay platelets stacked together. However, it seems that conventional processing and subsequent curing increases the tendency of reagglomeration of clay platelets (Fig. 7c). It can be noted here that the advantage of using the preexfoliated clay suspension to form NR nanocomposites is partially suppressed after conventional processing, as evident from the evolved morphology.
