Title:
THERMOPLASTIC ELASTOMER HAVING EXCELLENT RESILIENCE PROPERTIES AND HIGH STRENGTH AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/011725
Kind Code:
A1
Abstract:
Provided in the present invention is a preparation method for a thermoplastic elastomer having excellent resilience properties and high strength, the method comprising the following steps: A) placing at least two soft segment monomers in a solvent, adding a hard segment monomer, and allowing same to react under the action of a catalyst to obtain an initial reactant; and B) allowing the initial reactant to react with a chain extender to obtain a thermoplastic elastomer. The thermoplastic elastomer provided in the present application gains high strength and high modulus by means of the multiple hydrogen bonds in the hard segment monomer, and gains excellent toughness and high resilience by means of the thermodynamic incompatibility characteristic of the soft segment monomers. Therefore, the thermoplastic elastomer provided in the present application has the advantages of excellent strength and toughness, high resilience speed and high resilience rate.
