Synthesis and characterization of soy-based copolyamides with different α-amino acids

A series of soy-based copolyamides with different amino acid contents was synthesized by a condensation polymerization technique. The physical properties and enzymatic degradation properties were investigated. It was found that the introduction of amino acids into this type of copolyamide does not enhance the biodegradation ability but does improve the swelling properties of the copolyamides in water at a relative high pH and temperature. © 1999 John Wiley & Sons, Inc.
