Plexiglass is Poly(methyl 2-methylpropenoate), PVC is polyvinylchloride two totally different plastics. I can see no reason why they would be mixed. both a hard somewhat brittle plastics, plexiglass is clear unless dyed, while PVC is typically opaque. Either one may have a plasticizer added to make it more workable but this is seldom done with plexiglss.
