Abstract
The research about molecular weight and functional group analysis of low molecular weight liquid cyclic natural rubber has been done. The aim of this research is to achievement the quality of low molecular weight of liquid cyclic natural rubber. This research has been made in several steps such as preparation of the sample of rubber, the process of molecular degradation of cyclic rubber, and characterization of LCNR by using FTIR, GPC and viscosity test. Degradation is done with the help of the phenylhydrazine reagent with oxygen gas atmosphere with a flow rate of 2 LMin-1 for 24 hours. Molecular weight analysis by GPC had result the LCNR sample had a Mw is 60,556, a Mn is 6,661, and a PDI is 11,08613. The intrinsic viscosity can be used by relating it to the molecular weight by the Mark Houwink – Sakurada (MHS) equation and get the result 63.533 for LCNR molecular weight. The C-H stretching and bending region are two of the most difficult regions to interpret in infrared spectra. The ranges between 3300 to 2750 cm-1 is the C-H stretching region, is the more practical of the two regions. The frequency with which C-H bonds are obstructed is largely determined by the type of hybridization attributed to the bond. The stronger the vibrational force constant, the higher the vibration frequency.
