Abstract:
A manufacturing method of a thermoplastic polyester elastomer at least includes the following. An alcoholysis reaction is performed by using recycled polyethylene terephthalate with aliphatic diols to form an intermediate product. The intermediate product is bis 2-hydroxyethyl terephthalate. The intermediate product is used for a polymerization reaction with long chain polyalkyl glycols to form the thermoplastic polyester elastomer.
