This report documents the facile synthesis of mol. brushes, via a grafting onto approach, with potential application as coating binders. Firstly, alternating copolymers of Bu vinyl ether (n-BVE) and maleic anhydride (MAh), i.e. n-BVEMAh, were synthesized via conventional radical polymerization The anhydride reactive handle was subsequently utilized to access mol. brushes, via a grafting onto method, by imidizing the MAh repeat units with amine end-functional poly(ethylene glycol) oligomers, with 12 repeating units (PEG12-NH2). The product n-BVEMI-PEG12 brushes were viscous liquids at room temperature, hence we termed them liquid mol. brushes (LMBs). The LMBs displayed Newtonian flow behavior at shear rates below 1000 s-1. We evaluated the applicability of this mol. brush system as coating binder, by grafting varying fractions of linoleamide (Lin) side chains, which has oxidative crosslinking ability, along with the PEG12 onto n-BVEMAh, to access n-BVEMI-PEG12/Lin. The n-BVEMI-PEG12/Lin binders underwent oxidative crosslinking at 50 °C in the presence of a drier. The challenges associated with the current binder system are highlighted. In the experiment, the researchers used many compounds, for example, 1,3-Dicyclohexylurea (cas: 2387-23-7Computed Properties of C13H24N2O).
1,3-Dicyclohexylurea (cas: 2387-23-7) belongs to amides. The solubilities of amides and esters are roughly comparable. Typically amides are less soluble than comparable amines and carboxylic acids since these compounds can both donate and accept hydrogen bonds. Tertiary amides, with the important exception of N,N-dimethylformamide, exhibit low solubility in water. Amides can be freed from solvent or water by drying below their melting points. These purifications can also be used for sulfonamides and acid hydrazides.Computed Properties of C13H24N2O
