摘要：
A process of controlling the molecular weight and dispersity of poly(p-ethylphenol) and poly(m-cresol) synthesized enzymatically by varying the composition of the reaction medium. Polymers with low dispersities and molecular weights from 1000 to 3000 are synthesized in reversed micelles and biphasic systems. In comparison, reactions in bulk solvents resulted in a narrow range of molecular weights (281 to 675 with poly(p-ethylphenol) in a DMF/water system and 1,400 to 25,000 with poly(m-cresol) in an ethanol/water system). Poly(p-ethylphenol) was functionalized at hydroxyl positions with palmitoyl, cinnamoyl, and biotin groups.
