POLY 714 |
| Polyamides are well-known industrial products having applications in a variety of areas. The current work produces polyamide resins by enzyme-catalyzed polymerization of diester and diamine monomers. For example, a water-soluble polyamide can be produced via lipase-catalyzed polymerization of dimethyl adipate and ethylene triamine at 24-110oC. The enzymatic reaction is easy to do and applicable to a wide range of diacids and diamines. In addition, this enzymatic reaction permits the synthesis of several new high-molecular-weight polyamides that cannot be made through conventional chemical methods. Examples of new polymers are the polyamides from diethylene triamine and malonate, and diethylene triamine and fumarate. |
