This invention relates a composition comprising:

Elastomeric compositions

Elastomeric compositions comprising vinylaromatic block copolymer, polypropylene, plastomer, and low molecular weight polyolefin

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&#xb0; C. of at least 175 N/m (1 lb/in) and a T-Peel adhesion on a non-polar substrate at 20&#xb0; 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.

Functionalized propylene copolymer adhesive composition

Disclosed herein is 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%; and a functionalized polymer component comprising a C-Colefin comprising at least 0.1 wt % of a functional group; wherein the adhesive composition has a T-Peel adhesion on a polar substrate at 20&#xb0; C. of at least 175 N/m (1 lb/in) and a T-Peel adhesion on a non-polar substrate at 20&#xb0; 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 than the polarity of the non-polar substrate. Methods to produce the adhesive and articles comprising the adhesive are also disclosed.

Plasticized functionalized propylene copolymer adhesive composition

Branched crystalline polypropylene compositions and methods for the preparation of branched crystalline polypropylene compositions are provided. For example, described herein is a process of preparing a branched crystalline polypropylene composition that includes combining two or more different metallocene catalyst compounds with a polymerization medium that includes propylene, for a time sufficient to provide branched crystalline polypropylene that has from 0.0 wt % to 2.0 wt % ethylene and a heat of fusion of 70 J/g or more.
