The first surface includes first dimming portions, each of which includes two first side surfaces. Edges of the two first side surfaces away from the second surface intersect at a first intersection line. A surface of the second prism proximate to the second surface includes second dimming portions, each of which includes two second side surfaces. Edges of the two second side surfaces proximate to the second surface intersect at a second intersection line. A distance between orthographic projections of two adjacent first intersection lines on the second surface is less than a distance between orthographic projections of two adjacent second intersection lines on the second surface.

Abstract: A polymer composition that can exhibit excellent strength and flexibility under a variety of different conditions is provided. More particularly, the polymer composition contains a polyarylene sulfide, epoxy-functional polymeric impact modifier, and a crosslinking system that includes a metal carboxylate. In certain cases, the crosslinking system may also employ a crosslinking agent that is “multi-functional” to the extent that it contains at least two reactive, functional groups.
