Synthesis of Ultrahigh Molecular-Weight Poly(ethylene Terephthalate).
Abstract
This study was conducted to synthesize poly(ethylene terephthalate) or PET of number-average molecular weight of the order of 120 000. PET of number-average molecular weight of the order of 120 000 was prepared with a gas chromatograph apparatus through solid-state polymerization technology. PET particles were packed in the column, heated to a temperature somewhat below the melting temperature, and flushed with a carrier gas until the desired molecular weight was reached. Parameters studied were the catalyst, the particle size, the molecular weight of the starting material, the reaction temperature and time, and the flow rate and nature of the carrier gas.
