Abstract:
1. A transparent composition consisting of: a) from ≧20 wt % to ≦50 wt %, based on the weight of components a), b) and c), of a first polymer component (FPC) that includes polypropylene having a melting point (TM) ≧110° C.; b) from ≧10 wt % to ≦70 wt %, based on the weight of components a), b) and c), of a second polymer component (SPC) that includes a propylene polymer consisting essentially of 80 to 95 wt % units derived from propylene and from 5 to 20 wt % units derived from ethylene, including isotactically arranged propylene derived sequences and Tm <105° C. or a Heat of Fusion <45 J/g, or both; c) from 5 wt % to 20 wt %, based on the weight of the transparent composition of a hydrogenated hydrocarbon resin having a Tg ≧40° C. and ≦90° C., as determined by DSC, a polydispersity as measured by Mw/Mn of from 1.5 to 3.5, a softening point of from 120° C. to 180° C., as measured as a ring and ball softening point according to ASTM E-28; and d) an additive oil in an amount of from ≦15wt% based on the total weight of components a), b), c) and the additive oil; wherein the transparent composition has a:
