Mathcad ( versions 11 through 15 certainly) support saving the sheet file in 'HTML/MathML' format.
This means that you can view it with your internet browser. And it might just serve to export from Mathcad to FrameMaker.
If you really need this, you should do your work in Mathcad 15 (Note that your Prime license allows you to install and use Mathcad 15 to its full power, on the same computer), rather that waiting until in some future version Prime functionality catches up with that of 'real' Mathcad; let alone surpass it...
As far as I'm aware none of the Mathcad versions, neither 'real' Mathcad nor any version of Prime, supports out of the box any form of import ( by reading or pasting ) of mathematical functions, other than them just being pictures...
Only for Mathcad 11 there exists a possibility to transform a mathematical expression into a flat text string, that you can copy (out) and paste (elsewhere), as well as the other way around. But I guess that's not the type of information transfer that you're looking for.
Success!
