DETAILED DESCRIPTION OF THE PRESENT INVENTION: The present work focuses on the synthesis of a novel organic thermal stabilizer from PET waste. PET waste is degraded by aminolysis to work as thermal stabilizer for PVC. The products obtained were characterized and their structure was elucidated using FTIR, NMR, Mass spectroscopy. The PVC sheets were prepared using this organic thermal stabilizer. The organic stabilizer were used either alone or in combination with some metal stearates. PET waste (post consumer waste) is such as left over remains of the packaging products of beaverages plastic bottles, films made up of polyethylene terephthalate such as water and soft drink plastic bottles, cups containers etc. was collected, cleaned and cut into flakes. PET waste was then reacted with alkylamine (20% to 38% by weight) in the different ratio. Both the reactant were mixed in the reaction vessel and then it was sealed for 15 to 20 days. The reaction was carried out in the temperature range 20°C to 50°C. The white precipitate started appearing. When all the PET flakes were completely degraded, the reaction was filtered and white precipitate was washed with distilled water and dried in oven. The above reaction was carried out both in the absence and presence of catalyst. Catalysts employed were Zinc acetate, Zinc stearate, Lead stearate, quaternary ammonium salt etc. The product so obtained was then grinded to fine powder. This white powder was used as such in PVC compounding to work as thermal stabilizer. The quantity of thermal stabilizer was varied from 2 phr to 13 phr. The white precipitate was also used in combination with some metal stearates such as Magnesium stearate, Zinc stearate, Aluminum stearate, calcium stearate etc. to work as Thermal stabilizer. The result obtained using this white precipitate as thermal stabilizer was comparable with that of lead based stabilizer. 1.
