Running Acrobat 9 Professional and Word 2007 on a Windows XP SP-3 platform, I can't seem to preserve hyperlinks when saving a pdf in doc format. The native Save As function in Acrobat produces a Word document with content which is out of sequence, and the hyperlinks are lost. The on-line pdf-to-Word converters I have tried will produce a .doc or .docx file without disrupting the content, but the hyperlinks are lost. I am inexperienced with Acrobat, so there may be configuration settings I have overlooked.
Use the File > Export feature in Acrobat and select the text format of Microsoft Word Document. It should preserve the links.
This link should give some more detail on the options:
