Abstract: This invention relates a composition comprising: (i) at least one low molecular weight polyolefin; (ii) a block copolymer obtainable by selectively hydrogenating a block copolymer having terminal polymeric blocks of a vinyl aromatic monomer and a mid-block prepared originally with an olefin and subsequently hydrogenated; and (iii) polypropylene; (iv) with the proviso that when (i) is a PAO having a molecular weight of between about 400 and 1000 g/mole, either: (a) (iii) is a homopolymer characterized by an MFR greater than 2 g/10 min, (b) (iii) is a copolymer; or (c) (iii) is a polymer or copolymer made by a metallocene catalyst; or (d) the composition does not contain calcium carbonate.

Abstract: A composition comprising: (i) at least one low molecular weight polyolefin; (ii) at least one block copolymer obtainable by selectively hydrogenating a block copolymer having terminal polymeric blocks of a vinyl aromatic monomer and a mid-block prepared originally with an olefin and subsequently hydrogenated; (iii) at least one polypropylene; and (iv) at least one plastomer, wherein the plastomer is an ethylene based polymer having a density of 0.86 g/cc to about 0.910 g/cc or a propylene based polymer having a heat of fusion (Hf) of 70 J/g or less.

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.
