Claims
- 1. A biphenylene, terephenylene, naphthylene and/or anthracenylene containing dihalo-terminated poly(aryl ketone) oligomer having a molecular weight below about 10,000,
- wherein said dihalo-terminated oligomer comprises at least one formula selected from the group consisting of: ##STR42## Ph is 1,4-phenylene, Ph' is biphenylene, terphenylene, naphthylene and/or anthracenylene, each X is independently halogen and r is less than one and n is two or greater when ph' is terephenylene, naphthylene or anthracenylene and four or greater when ph' is biphenylene.
- 2. A dihalo-terminated oligomer as defined in claim 1 of the following formula: ##STR43## where Ph is 1,4-phenylene, Ph' is biphenylene, terphenylene, naphthylene and/or anthracenylene, and n is two or greater when Ph' is terephenylene, naphthylene or anthracenylene and four or greater when Ph' is biphenylene.
- 3. A dihalo-terminated oligomer as defined in claim 1 of the following formula: ##STR44## where Ph is 1,4-phenylene, with the proviso that where there are two carbonyl groups attached to the same Ph, up to 50 mole percent of these groups can be in the 1,3 position to each other.
- 4. A dihalo-terminated oligomer as defined in claim 1 of the following formula: ##STR45##
- 5. A dihalo-terminated oligomer as defined in claim 1 of the following formula: ##STR46## where r is less than one.
- 6. A dihalo-terminated oligomer as defined in claim 1 of the following formula: ##STR47##
- 7. A dihalo-terminated oligomer as defined in claim 1 of the following formula: ##STR48##
- 8. A dihalo-terminated oligomer as defined in claim 1 of the following formula: ##STR49##
- 9. A dihalo-terminated oligomer as defined in claim 1 of the following formula: ##STR50##
- 10. A dihalo-terminated oligomer as defined in claim 1 of the following formula: ##STR51##
- 11. A dihalo-terminated oligomer as defined in claim 1 of the following formula: ##STR52##
- 12. A dihalo-terminated oligomer as defined in claim 1 of the following formula: ##STR53##
- 13. A dihalo-terminated oligomer as defined in claim 1 of the following formula: ##STR54##
