    摘要： Polymer mixtures are disclosed which comprise at least one homogeneously branched ethylene polymer (A) and at least one ethylene polymer (B) having a crystallinity which is at least 7% greater than the crystallinity of polymer (A) with certain provisos. A process for making a molded article using the disclosed polymer mixtures is disclosed as well as films, film layers, coatings and molded articles formed from those mixtures. These mixtures have several advantages over polymer compositions of the prior art, including improved properties at elevated temperatures such as improved softening point under load, improved hardness, improved toughness, improved 100% modulus of elasticity, improved compression set, improved ability to prevent oil bleed out at lower temperatures when the mixture contains oil and reduced injection molding cycle time. The mixtures retain their performance advantages even when substantial amounts of additives such as oil and filler are incorporated into the mixture. The mixtures may also be crosslinked after they are formed into the shape of an article to form vulcanized elastomeric products. The polymer mixtures have utility in a variety of applications.

    摘要： Modified polymer compositions having good flowabilty, impact performance and modulus made from at least one polyolefin (e.g., high density polyethylene or polypropylene) blended with minor amounts of either at least one homogeneous linear ethylene/C.sub.5 -C.sub.20 .alpha.-olefin or at least one substantially linear ethylene/C.sub.3 -C.sub.20 .alpha.-olefin polymer are disclosed. The compositions are suitable for thermoformed or molded thinwall applications such as drinking cups, lids, and food containers where the flow length to wall thickness ratios are greater than about 180:1. A process of making thin wall articles is also disclosed.

    摘要： A polymer composition comprises at least an ethylene/α-olefin interpolymer and at least one other polymer. The other polymer can be selected from a second ethylene/α-olefin interpolymer, an elastomer, a polyolefin, a polar polymer, and an ethylene/carboxylic acid interpolymer or ionomer thereof. The ethylene/α-olefin interpolymer is a block copolymer having at least a hard block and at least a soft block. The soft block comprises a higher amount of comonomers than the hard block. The block interpolymer has a number of unique characteristics disclosed here. Also provided are gaskets, bottle cap liners, and closures that comprise or obtained from a compositon comprising at least one ethylene/α-olefin interpolymer and at least one polyolefin. The gaskets are capable of compression sealing various containers, without contaminating the contents. Liquid containers particularly benefit from the use of the novel gasket materials disclosed herein.
