Claims
- 1. A bis(acid chloride)-terminated poly(aryl ketone) oligomer having at least three repeating units comprising one or more divalent aromatic radical indepenently selected from the group consisting of biphenylene, terphenylene, naphthylene and antracenylene having a number average molecular weight below about 10,000.
- 2. A bis(acid chloride)-terminated oligomer as defined in claim 1 of the following formula: ##STR57## where Ph is 1,4-phenylene with the proviso that where there are 2 carbonyl groups attached to the same Ph, up to 50 mol % of these groups can be in the 1,3 position to each other, where n is an integer larger than 1.
- 3. A bis(acid chloride)-terminated oligomer as defined in claim 1 of the following formula: ##STR58## where Ph is 1,4-phenylene with the proviso that where there are 2 carbonyl groups attached to the same Ph, up to 50 mol % of these groups can be in the 1,3 position to each other, where n is an integer larger than 1.
