WebMar 1, 2024 · In the initial degradation of PET dimer, the concerted reaction is the main pyrolysis reaction, and terephthalic acid, vinyl terephthalate, divinyl terephthalate formed by concerted reactions may be main pyrolysis products. The radical reaction is the main competitive pyrolysis reaction. WebModified poly (ethylene terephthalate) contains co-monomers, such as ether, amide or aliphatic monomers that provide “weak” linkages that are susceptible to biodegradation through hydrolysis.1 The mechanism involves a combination of hydrolysis of the ester linkages and enzymatic attack on ether and amide bonds. 1 With modified PET it is …
