Simple adhesive coacervates and methods of making and using thereof
First Claim
1. An adhesive produced by the process comprising(a) preparing a simple adhesive coacervate comprising (1) a polyelectrolyte, wherein the polyelectrolyte comprises a polyanion or polycation but not a combination thereof, the polyeletrolyte comprises at least one crosslinking group, and wherein a photoinitiator and optionally a co-initiator are covalently attached to the polycation and/or polyanion, (2) a sufficient amount of a complimentary counterion to produce a simple adhesive coacervate, and (3) a polymerizable monomer, a water-insoluble filler, or a combination thereof;
- and(b) crosslinking the simple adhesive coacervate to produce the adhesive.

Abstract
Described herein is the synthesis of adhesive from simple adhesive coacervates and their uses thereof. The adhesives are produced by (a) preparing a solution comprising (1) a polyelectrolyte, wherein the polyelectrolyte comprises a polyanion or polycation but not a combination thereof, the polyeletrolyte comprises at least one crosslinking group, and (2) a sufficient amount of a complimentary counterion to produce a simple adhesive coacervate; and (b) crosslinking the simple adhesive coacervate to produce the adhesive. The adhesives have numerous medical and non-medical applications.
