In a partitive construction, reflexives do not usually occur:
Julie and Bob are talking about the two of them/*themselves.
The following example is from COCA:
The men, all of them, stared into their cups.
In the above sentence, the pronoun them refers to the men. Ideally, reflexives should be able to appear when anaphoric relations are formed. For what reason do the reflexives eschew partitive structures? Thanks in advance for any comments or answers.
