Abstract
This invention relates to an adhesive composition comprising a functionalized random propylene polymer (FRPP) having at least 0.1 wt % of a functional group, a heat of fusion of between 0.5 and 70 J/g, and an mm triad tacticity index of at least 75%, where the adhesive 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 (1 lb/in) where the polarity of the polar substrate is at least 0.10 units higher than the polarity of the non-polar substrate. Methods to produce the adhesive and articles comprising the adhesive are also disclosed.
