Without getting into any chemistry, they are from different sources. Acrylic is a synthetic polymer from the petro-chemical industry. Common forms would be Lucite and Plexiglass. Acetate is a natural polymer that was originally processed from trees and cotton. The most recognized forms of Acetate would be rayon, celluloid used in photographic film, and nitro-cellulose lacquer.

As we see them in pen blanks, they are two plastics with similar properties. Acrylic is more brittle than Acetate, and that would make the Acetate the easier to turn on a lathe. Both are soluble in Acetone.
