Abstract
A composition comprises an oligomer synthesized from a multifunctional monomer, a diol, and an amino acid synthesized by reacting (i) a multifunctional monomer comprising citric acid or triethyl citrate with (ii) a diol to form a reaction product, and further reacting the reaction product with (iii) an amino acid. Examples of the diol include 1,8-octanediol, ethylene glycol, and poly(ethylene glycol). Examples of the amino acid include cysteine and serine. Further, the amino acid is linked as a side group to the oligomer backbone.

A composition comprising:
- an oligomer synthesized by reacting (i) a multifunctional monomer comprising citric acid or triethyl citrate with (ii) a diol to form a reaction product, and further reacting the reaction product with (iii) an amino acid,
- wherein the amino acid is linked as a side group to the oligomer backbone.
A composition comprising:
- an oligomer synthesized by reacting (i) a multifunctional monomer comprising citric acid or triethyl citrate with (ii) a diol to form a reaction product, and further reacting the reaction product with (iii) an amino acid and (iv) a di-isocyanate wherein the amino acid is linked as a side group to the oligomer backbone.
A method of making a composition, the method comprising:
- mixing (i) a multifunctional monomer comprising citric acid or triethyl citrate and (ii) a diol to form a mixture;
- raising the temperature of the mixture to at least 80° C.
- forming an oligomer from the mixture;
- and
- reacting an amino acid and, optionally, a di-isocyanate with the oligomer;
- wherein the amino acid is linked as a side group to the oligomer backbone.
