Title:
ESTER-AMIDE MULTI-BLOCK COPOLYMER, METHOD FOR PRODUCING ESTER-AMIDE MULTI-BLOCK COPOLYMER, ESTER-AMIDE COPOLYMER, AND METHOD FOR PRODUCING ESTER-AMIDE COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2023/238706
Kind Code:
A1
Abstract:
Provided is an ester-amide multi-block copolymer represented by formula (1), which comprises a block containing a polyester and a block containing a polyamide obtained through ring opening polymerization of a cyclic lactam. (R1 and R2 each denote a hydrogen atom or a substituent group-containing alkyl chain having 1-20 carbon atoms, and R3 denotes a hydrogen atom or a substituent group-containing alkyl chain having 1-10 carbon atoms. In addition, R4 is an aromatic hydrocarbon chain that does, or does not, contain a heteroatom or an aliphatic hydrocarbon chain that does, or does not, contain a hetero atom. Y is NH, O or S. Furthermore, m denotes an integer between 1 and 60, n denotes an integer between 1 and 120, l denotes an integer between 2 and 100, and x denotes an integer between 1 and 11). Also provided is a method for producing the multi-block copolymer.
