Abstract
A polymer composition providing optical clarity and impact resistance includes from about 40 weight percent (wt. %) to about 99.9 wt. % (e.g., 50-95 wt. %) of a continuous matrix, and from about 0.01 wt. % to about 60 wt. % (e.g., 5-50 wt. %) of a dispersed phase. The weight percentages of the matrix phase and the dispersed phase are based on the total weight of the matrix phase and the dispersed phase. The matrix phase may comprise a polypropylene polymer comprising from 0 to 7 mole percent (mol. %) of units derived from ethylene, a C4-C10 alpha olefin or combinations thereof. The dispersed phases may be a propylene/alpha olefin copolymer having from 10 mol. % to 70 mol. % of units derived from ethylene or a C4-C10 alpha olefin or combinations thereof.
