I have found Cyanoacrylate works well with perspex.
It appears to solvent weld it, as well as polymerising.
With care, you can bond two transparent pieces together
with the bond being invisible when you look through it,
and if you pull it apart, the perspex breaks before the
bond separates.

I was amazed at your claim. I haven't any superglue in the house, but
do have a bottle of Loctite SuperGlue3 remover dated 1994. I tried
this and it worked as you describe after an hour or so!
