UNSATURATED POLY(ESTER-AMIDE) AND POLY(ETHER ESTER AMIDE) BIOMATERIALS

摘要

Functionalized poly(ester-amides) and poly(ether ester amides) polymers having the structural formula:; wherein R¹ is (C₂-C₂₈)alkylene, or (C₂-C₂₈)alkylene substituted with a side chain selected from the group consisting of (2-carboxyethyl)thio, (2-hydroxethyl)thio, (2-aminoethyl)thio and (2-aminoethyl)thio hydrochloride sa R³ is selected from the group consisting of hydrogen, (C₁-C₆)alkyl, and (C₆-C₁₀)aryl (C₁-C₆)alkyl; and R⁴ is selected from the group consisting of (C₂-C₂₈)alkyloxy, (C₂^-C₂₈)alkylene substituted with a side chain selected from the group consisting of (2-carboxyethyl)thio, (2-hydroxethyl) thio, (2-aminoethyl)thio and (2-aminoethyl)thio hydrochloride salt, and —C₂H₄(OC₂H₄)_x; x ranges from 2-4; n ranges from 5 to 150; and wherein at least one of R1 and R4 attaches a functional group.
