A method for altering the transparency of a stable hexagonal polymorphic poly(butene-1) obtained from unstable tetragonal crystalline poly(butene-1) comprising contacting the tetragonal crystalline poly(butene-1) with a volatile solvent for a short time, then removing from the solvent, and allowing solvent adhereing to the poly(butene-1) to evaporate. The finished polymer can be opaque, transparent, or translucent depending upon the solvent and temperature used.
