The properties of polyol were varied by their initiator:co-initiator weight ratio. The completion of polyol formation was characterized through Fourier Transformation Infrared (FTIR) spectroscopy. Other parameters such as acid number and hydroxyl number of polyol were also studied to monitor the progress of reaction. FTIR results showed the significant changes particularly for the OH and C=O stretching peaks. � (2012) Trans Tech Publications, Switzerland.en-USFourier Transformer Infrared (FTIR) spectroscopyHydrolysis resistantPolycaprolactone (PCL)/palm kernel oil based polyolRing opening polymerizationAcid numbersCaprolactoneFourierFTIRHydroxyl numberOil-based polyolPalm kernel oilWeight ratiosFourier transform infrared spectroscopyFourier transformsHydrolysisManufactureOil filled transformersPolycaprolactoneRing opening polymerizationAlcoholsConference Paper334337576
