Method for manufacturing crosslinked polyetherester resins

摘要

The invention relates to a method for producing crosslinked polyetherester resins having high heat resistance and mechanical strength, high flexibility and elongation. The aim of the invention is introducing long-chain polyether blocks of the following formula [O-CHR-(CH2)m-CH2]n . where R=H, CH3, or C2H5, n=2-15 and, m=0-4 into the chains of polyesters obtained by the reaction of acids or anhydrides, in particular the Diels-Alder adduct of maleic anhydride with 2-naphthol.
