Cellulose nanocrystals can enhance nucleation activity in materials made from these molecules. Examples of these molecules that can conduct electricity include P3HT. The Kuhn length of these molecules is a function of dihedral bond angle. Distribution of components in these molecules can be analyzed with the Mayo–Lewis equation. These molecules, which can follow the Flory–Schulz distribution, have (10[1])a step-growth mechanism characterized (10[2])by the Carothers (“ker-OTHERS”) equation. One way to characterize these molecules is by calculating the ratio of the number-average molecular weight to that of M0 (10[1])(“M-naught”). For 10 points, name these molecules that consist of long repeating (10[1])chains. (10[1])■END■
