While the previous poster was very adept at cutting and pasting from wikipedia, they failed to answer the question.
The answer is no, polio viruses are not enveloped.

The poliovirus itself is a small RNA (ribonucleic acid) virus related to Hepatitis A. There are three separate quasi-species and all are extremely infectious. The virus is known as a picornavirus. It is not only an RNA virus, but one with a very small RNA genome - about 7-8 kilobases long. It is widely regarded as the simplest significant virus, because of its short genome and the fact it is made up of nothing more than this RNA and the capsid enclosing it.
Picornaviruses are viruses that belong to the family Picornaviridae. The name picornavirus means small RNA virus. Picornaviruses are non-enveloped, positive-stranded RNA viruses with an icosahedral capsid. The genome RNA is unusual because it has a protein on the 5' end that is used as a primer for transcription by RNA polymerase.
Please see the web pages for mre details on Poliomyelitis and Picornavirus.
