Abstract:
1. An adhesive composition comprising: a random propylene polymer component having a heat of fusion of between 1 and 70 J/g and an mm triad tacticity index of at least 75%; a functionalized polymer component comprising a C a non-functionalized plasticizer, wherein the adhesive composition has a T-Peel adhesion on a polar substrate at 20° C. of at least 175 N/m (1 lb/in) and a T-Peel adhesion on a non-polar substrate at 20° C. of at least 175 N/m Pa (1 lb/in) and where the polarity of the polar substrate is at least 0.10 units higher that the polarity of the non-polar substrate.
