BIO-BASED POLYAMIDE ELASTOMER AND PREPARATION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2023/025284

Kind Code:

A1

Abstract:

Disclosed is a bio-based polyamide elastomer and a preparation method therefor. The bio-based polyamide elastomer is prepared by using as monomers specific aliphatic diacid and pentanediamine prepared by a biological method. The polyamide elastomer of the present invention has excellent performance and a stable polymerization monomer source, solves the problem of the excessively high cost of polyamide elastomer, broadens the usage scenarios for elastomers, and has very high commercial value.
