Abstract
A modified thermoplastic polyester elastomer and a breathable and waterproof membrane are provided. The modified thermoplastic polyester elastomer is formed from a thermoplastic polyester elastomer, a regenerated polyethylene terephthalate, and a compatibilizer. Based on a total weight of the modified thermoplastic polyester elastomer being 100 phr, a content of the regenerated polyethylene terephthalate is greater than 0 phr and up to 50 phr. Based on a total weight of the thermoplastic polyester elastomer being 100 wt %, the thermoplastic polyester elastomer includes 25 wt % to 75 wt % of hard segments and 25 wt % to 75 wt % of soft segments.
