Diblock polymers are known to self-assemble into a variety of structures, and the effects of block mol. weights and volume fractions, along with the interactions between chem. different blocks, have been extensively studied. However, the consequences of mol. architectural differences between the blocks on phase behavior, particularly self-assembly into network morphologies, are less well explored. In this work, 223 linear-bottlebrush diblock polymers were synthesized using grafting-through living ring-opening metathesis polymerization The linear block was poly(norbornene exo,exo-dimethyl ester), while five different bottlebrush blocks were used in order of increasing side-chain length: poly(norbornene exo,exo-di-isoamyl ester), poly(norbornene exo,exo-di-3,7-dimethyloctyl ester), poly(norbornene exo,exo-di-hexahydrofarnesyl ester), poly(norbornene exo,exo-di-dihydrophytyl ester), and poly(norbornene exo,exo-di-perhydrosolanesyl ester). Diblock polymer compositions ranged from approx. 30 to 70% by volume of the linear block, with total backbone ds.p. ranging from 30 to 140, and side chains containing 5-45 carbon atoms. Phase behavior was studied in the vicinity of the double gyroid network window using a combination of small-, mid-, and wide-angle X-ray scattering. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8HPLC of Formula: 106-21-8).
3,7-Dimethyloctan-1-ol (cas: 106-21-8) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.HPLC of Formula: 106-21-8
