| titleOfInvention | Method for producing shielded polyarylene ether |
| abstract | The present invention relates to a process for preparing a polyarylene ether (polyarylene ether A ') comprising reacting a polyarylene ether (polyarylene ether A') having a repeating unit represented by the following formula (Iaa) and a terminal hydroxyl group with a phthalic anhydride represented by the following formula (III) in a solvent in the presence of potassium fluoride (Polyarylene ether A) having a repeating unit of the following formula (II) and a terminal anhydride group of the following formula (II).n n n ≪ Formulan n n n n n n n ≪ Formula (II)n n n n n n n n ≪ Formula (III)n n n n n n n n Wherein,n n n t and q are integers 0, 1, 2 or 3; T, Q and Z are each independently selected from the group consisting of a chemical bond or -O-, -S-, -SO 2 -, S═O, C═O, -N═N-, -R a C═CR b -, and -CR c R d - Kii are, selected from the t-stage, at least one of the q or Z groups is -SO 2 - or C = O and, if t and q are 0 Z is -SO 2 - or is C = O, R a and R b is a hydrogen atom or C 1 -C 10 -alkyl, R c and R d are hydrogen, C 1 -C 10 -alkyl, C 1 -C 10 -alkoxy or C 6 -C 18 -aryl, Groups may be replaced by fluorine and / or chlorine atoms, or may form a C 4 -C 7 -cycloalkyl group which may be substituted with one or more C 1 -C 6 -alkyl groups, together with the C atom to which they are attached, and, Ar and Ar 1 is optionally substituted or a C 1 -C 10 - alkyl, C 6 -C 18 - aryl, C 1 -C 10 - which may be substituted by alkoxy or halogen C 6 -C 18 - aryl, , And X is fluorine, chlorine, bromine or iodine. |
