Help>Apropos readonly:

  is_readonly set_line_readonly set_readonly toggle_readonly

I would recommend 

  M-x view-mode
  
(with view-mode from jedmodes.sf.net/mode/view/) which sets the buffer to ro
uses a "view" keymap but keeps the syntax highlight.

Remember, that you cannot have split view of a buffer but not have one in
view ro and the other rw.
