Abstract
Lipases and proteases from various sources were tested in aromatic pol yester synthesis in organic solvents. A commercial protease from Bacil lus licheniformis efficiently catalyzed the transesterification of a d iester of terephthalic acid and 1,4-butanediol in anhydrous tetrahydro furan (THF). This protease was used as a catalyst in the synthesis of aromatic polyesters in THF. Oligomers with average molecular weights f rom 400 to 1000 daltons were obtained using various diols and aromatic diesters.
