Abstract

Depolymerisation of post-consumed PET bottle during in situ transesterification with BMT and EG was studied and the kinetics of transesterification, thermal, mechanical properties of samples prepared at different PET scrap contents were investigated. Transesterification conyersion, calculated from effluent methanol, decreased as PET scrap content increased in the reaction mixture. The mechanical properties of PET prepared with 20, 3owt% PET scrap were similar to the original PET but decreased at PET scrap content of 40w1ole and in the case of ORP. Thermal properties were similar to original PET at all PET scrap contents. Intrinsic viscosity was found to decrease at 40% and ORP but found to be higher in other cases. X-ray diffraction patterns of bottle and samples containing PET showed different peaks from the original PET.
