In this research, we introduce a novel approach that significantly accelerates the solid-state polymerization (SSP) of poly(ethylene terephthalate) (PET) by reducing the thickness of PET chips using a heating roller. This process results in thinner PET chips, which demonstrate accelerated diffusion rates of water and ethylene glycol, the primary by-products of the SSP process. As a part of our methodical study, PET chips of varying thicknesses were prepared and subsequently analyzed to assess the correlation between their thickness and both the rate of polymerization and crystallization characteristics. Our findings suggest that this adjustment in the PET SSP process has the potential for broader application in the polymer industry, paving the way for a more efficient, sustainable, and economical mode of production.
