Abstract: Synthesis methods for creating polymeric compounds comprising dihydroxyphenyl derivatives (DHPD), or DHPp i.e. polymers modified with DHPD, with desired surface active effects are described. The polymer backbone of DHPp has structural or performance features that can be tailored to control physical properties of DHPp, allowing it to be useful for different applications i.e. tissue adhesives or sealants, adhesion promoting coatings, and antifouling coatings.

Abstract: 3,4-Dihydroxyphenyl-L-alanine (DOPA) is an unusual amino acid found in mussel adhesive proteins (MAPs) that form tenacious bonds to various substrates under water. DOPA is believed to be responsible for the adhesive characteristics of MAPs. This invention relates to a route for the conjugation of DOPA moieties to various polymeric systems, including but not limited to poly(ethylene glycol) or poly(alkylene oxide) systems such as poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) block copolymers.
