Abstract


Polymerization of purified eugenol from clove leaf oil using concentrated sulfuric acid as catalyst has been done in this research. Clove leaf oil was purified by vacuum redistillation, acid-base extraction, and vacuum fractionation to yield eugenol. The eugenol was polymerized with concentrated sulfuric acid in ratio 1: 2. Polyeugenol from eugenol of clove leaf oil resulted from redistillation, extraction, and fractionation is in solid form (yield: 88.14%); from redistillation and extraction is also in solid form (yield: 86.15%); from redistillation clove leaf oil is in gel form (yield: 100.29%). Structure of polyeugenol was determined by infrared spectrophotometer and characterized by thin layer chromatography (TLC). Molecular weight of the product was calculated by viscometry method.
