Patent ID: 11421088

Abstract:
A method of preparing thermoplastic polyester elastomer membrane with high binding strength includes the following steps: (a) Adding a reaction solvent to TPEE powder or granules to prepare a solvent mixture. (b) Adding a modifier to the solvent mixture, and mixing uniformly to prepare a first mixture, the modifier including at least one of o-xylylenediamine, m-xylylenediamine, alpha,alpha′-diamino-p-xylene, 2,3,5,6-Tetrachloro-p-xylene-alpha,alpha′-diamine, and 1,3,5,7-Tetraazatricyclodecane. (c) Adding an initiator to the first mixture, and mixing uniformly to prepare a second mixture. (d) Obtaining a finished product by passing the second mixture through an injection laminating process.
