Methacrylate comb polymers were synthesized that have amphiphilic teeth of ethylene glycol oligomers capped with alkyl groups. Both segments are of exact length to promote self-organization and crystallization The atactic methacrylate backbone plus close proximity to the polymer backbone inhibits crystallization of the oligoethylene oxide segments, but the terminal alkyl segments readily crystallize. Wide-angle X-ray diffraction and differential scanning calorimetry were used to characterize polymer side chain crystallization and its evolution as a function of the length of the amphiphilic teeth. An anal. of the d spacings places the oligoethylene glycol segment and the first eight carbon atoms of the alkyl chain in an amorphous phase. An ∼1 Å/carbon atom increase in the d spacing is consistent with the crystalline segments being tilted relative to the polymer backbone. When the number of carbon atoms in alkyl segments is ≥14, addition of LiClO4 yields an ionic conducting ethylene oxide phase with retention of the alkyl crystallization These novel polymer electrolytes use crystallization as a structural element to maintain dimensional stability. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Category: ethers-buliding-blocks).
2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
