Monona is right, look at the individual glove manufacturer for testing permeation and degradation information. If you do a Google search, you'll end up with generic information that will be unreliable - depending upon which glove has been specified.
Suppliers and Google will provide generic "data" but nothing I would rely upon when you really need to confirm adequate protection.
It's late and I can't remember the name of the organic chemist who started the testing work at Ansell. He developed the first spreadsheet, which later turned into their database. When I ran into a new molecule that was going to be tested for toxicity as an investigational new drug, if he could not refer to a very close analog to provide protection, I could send him a sample and he would test to provide a recommendation. It depends upon what you are trying to protect against. Is a generic, possibly diluted level of protection adequate or are you trying to protect from a true hazard?
