TL;DR: In this article, the authors proposed a block structure of A-B-A type, where A is a plastomeric segment and B is an elastomerical segment.
Abstract: Compositions containing fluorinated thermoplastic elastomers with different moelcular weight and with different plastomeric phase/elastomeric phase ratio, essentially formed by: (a) 30-80% by weight, preferably 50-80%, of a fluorinated thermoplastic elastomer, having a block structure of A-B-A type, wherein A is a plastomeric segment and B is an elastomeric segment; (b) 10-50% by weight, preferably 20-40% of a fluorinated thermoplastic elastomer having a block structure of A-B-A type; (c) 0-30% by weight, preferably 0-15%, of a fluorinated plastomer preferably of the same kind as that contained in the component (a) and/or (b).

TL;DR: In this article, a self-adhering film material made from a blend of metallocene polymers was proposed for sealing and wrapping applications, which are useful for sealing applications.
Abstract: Compositions comprising a blend of a MPEP (metallocene catalyzed polyethylene plastomer) and a MPEE (metallocene catalyzed olefin copolymer elastomer); self-adhering film materials made from a blend of these metallocene polymers; and methods of making these self-adhering film materials which are useful for sealing and wrapping applications.

TL;DR: A thermoplastic polymer composition incorporating at least 50 wt % polypropylene, at least 20 wt% of an elastomer such as EP rubber and at least about 4 Wt % plastomer is used to produce large components such as bumpers and exterior trim fascia for automobiles as mentioned in this paper.
Abstract: A thermoplastic polymer composition incorporating at least about 50 wt % polypropylene, at least about 20 wt % of an elastomer such as EP rubber and at least about 4 wt % plastomer. The plastomer is preferably a single site catalyzed ethylene based copolymer having a density less than about 0.915. By adjusting the amount of the plastomer in the composition, considerable control is secured over post-mold shrinkage of components produced through injection molding operations utilizing the composition. The composition can be prepared as a reactor blend or a melt blend. The composition is particularly useful in producing large components such as bumpers and exterior trim fascia for automobiles.

TL;DR: In this paper, a polymer blend of isotactic polypropylene and reactor grade propylene based elastomers or plastomers was used to construct yarns with superior abrasion resistance and excellent softness characteristics.
Abstract: The present invention relates to nonwoven webs or fabrics. In particular, the present invention relates to nonwoven webs having superior abrasion resistance and excellent softness characteristics. The nonwoven materials comprise fibers made from of a polymer blend of isotactic polypropylene, reactor grade propylene based elastomers or plastomers, and optionally, a homoge-neously branched ethylene/alpha olefin plastomer or elastomer. The isotactic polypropylene can be homopolymer polypropylene, and random copolymers of propylene and one or more alpha-olefins. The reactor grade propylene based elastomers or plastomers plastomer have a molecular weight distribution of less than about 3.5, and a heat of fusion less than about 90 joules/gm. In particular, the reactor grade propylene based elastomers or plastomers contains from about 3 to about 15 percent by weight of units derived from an ethylene, and a melt flow rate of from about 2 to about 200 grams/10 minutes. The present invention also relates to cold drawn textured fibers comprising of a polymer blend of isotactic polypropylene and reactor grade propylene based elastomers or plastomers.
