On the basis of mechanism, there are two types of polymerization; step-growth and chain-growth polymerization. But, if it’s so durable and resistant to breaking down, where does all that plastic go when we’re done with it? The basic building blocks of PET are ethylene glycol and terephthalic acid, which are combined to form a polymer chain. As several benefits seemed to be related to the use of this material (less damaged blood cells, no or little protein depletion, no or few clot deposition, neither embol release), he tried with his team to extend its applications. Few ruptures or tears were observed but had been likely caused either by a bad handling or by fibrosis expansion, the latter being more frequent for non‐sheathed devices (Formichi et al. The former is a transesterification reaction, whereas the latter is an esterification reaction. We use PET containers in our day to lives, whether it be making a sandwich or buying a bottled water from the store. There is plastic in our drinking water. PET bottles are stretch-blow molded, the stretching or biaxial orientation being necessary to get maximum tensile strength and gas barrier, which in turn enables bottle weights to be low enough to be economical. Such resins may be classified as low-viscosity or high-viscosity resins. Among others, DuPont Engineering Polymers and DSM have launched Hytrel RS and Arnitel ECO thermoplastic elastomers providing characteristics (see Table 10.31) similar to those of fossil thermoplastic elastomer esters, while offering a more environment-friendly solution than products that are entirely petroleum-based. Main applications could be those of traditional PET and characteristics should be similar. Good gas and moisture barrier properties, Coefficient of thermal expansion (10–5/°C), General chemical properties are subject to the compatibility of the fillers and reinforcements with the ambient conditions.
