Development of Poly−Cyclohexanone Resin Material for Coating Applications

Abstract

In the present work, polymerization reactions of cyclohexanone were carried out in a high−pressure reactor. The effect of reaction parameters such as reaction time, temperature, and catalyst loading on hydroxyl value, iodine value, solubility, and average molecular weight of products was investigated. In the study, reaction time was varied from 10−17 hrs, reaction temperature was varied from 130−150 °C, catalyst concentration was varied from 20−40%. The result shows that the degree of polymerization and hydroxyl value of the products increases with the increase of reaction time, temperature and catalyst loading. As the degree of polymerization increases, the decrement in product solubility in a given solvent was observed. FTIR, GPC and TGA analysis was done for the developed products. Based on the present study, it is concluded that the in−house developed resin from cyclohexanone can be used for coating applications.
