| titleOfInvention | Thermoplastic polyester elastomer and preparation method thereof |
| abstract | The invention discloses a thermoplastic polyester elastomer, which is prepared from 2, 5-furandicarboxylic acid or 2, 5-furandicarboxylic acid dimethyl ester, branched chain short-chain diol and hydroxylThe end-capped oligomer is used as a main raw material and is prepared by a polycondensation method under the action of a catalyst, and the structural formula is shown as the formula (I): in the formula, m and n respectively represent the number of the structural units of the hard segment and the soft segment, and n/(m + n) is more than or equal to 0.01 and less than or equal to 0.99; r is selected from branched alkyl containing 3-5 carbon atoms in a main chain, X is selected from oligomer, and a repeating unit is a pure carbon chain containing 2-10 carbon atoms or a carbon chain containing Si and/or O heteroatoms. The invention adopts bio-based source compounds as raw materials, obtains a novel thermoplastic polyester elastomer through molecular design, and the elastomer has extremely high initial deformation recovery rate and elongation at break. |
