Catechol functionalized polymers initiator

Figure 10.6 Schematic representation of polymer preparation using catechol-modified and polymerizable monomers (A) and using a polymer-bound initiator to form a block copotymer (B). In the presence of bi-functional crosslinkers, potymerization forms a three-dimensional pol3mier network containing catechol (C). R represents the side chain of the monomers used to copotymerize with the catechol-functionalized monomers.

Figure 10.4 Diversity of chemistiy structures utilized to create biomimetic adhesive polymers. Catechol side chain (A) modification alters its interfacial binding strength and reactivity. Substitution can be achieved by replacing -H at the para position with chloro-(B), nitro- (C) and hydrojyl (D) groups or a hydro)yl group at the meta position (E). The benzene ring can be substituted with a pyridine group (F). Linking the catechol with a polymer can be achieved via reaction of the amino acid (G), acid (H), or amine (I) groups. Catechol modified with a bromide propionamide Initiator to initiate polymerization (J) or functionalized with polymerizable methacrylamide (K), vinyl (L), and M-carboxyanhydride (NCA, M) groups.
