Abstract
Polymer compositions and articles formed therefrom are described herein. The compositions include a random copolymer and a radiation additive, wherein the random copolymer includes propylene and less than 2 wt. % ethylene and exhibits a melt flow rate of from about 30 to 100 dg/min., the polymer composition exhibits a flexural modulus of from about 160 kpsi to about 200 kpsi and the polymer composition is adapted to produce a polymer article exhibiting low plate out, a haze at 20 mils of no greater than 15%, radiation stability and autoclavability.
