I looked up Polaroid TV code files in a few different on-line collections of IR signals. Each model I found had a totally different code set. One had Hitachi's standard code set, another had Panasonic's, another had Mitsubishi's. Others had code sets I don't recognise.

UEI is pretty good at building up their own internal library of code sets by brand, so maybe the 14 code sets Edmund mentioned covers it (so with a few tries with phone upgrades for an 8910 you'd get it solved). But the available on-line data for Polaroid code sets makes me less confident of that.
