Abstract
The subject invention is directed to polymer compositions having improved bond performance, to a method for improving the bond performance of a polymer composition, and to fabricated articles, such as fibers and fabrics which exhibit an improved bond performance, and to other fabricated articles, including but not limited to rotationally molded articles, prepared from polymer compositions of the invention.
Claims11
A rotational molded article comprising a polymer composition having improved bond strength which in turn comprises:
- a. from 0.5 percent to less than 15 weight percent (by weight of the polymer blend) of a first polymer which is a homogeneous ethylene/α-olefin interpolymer having
- i. a melt index of from 0.1 to 100 grams/10 minutes,
- ii. a density of from 0.855 to 0.890 grams/centimeters3, and
- b. a second polymer which is an ethylene homopolymer or an ethylene/α-olefin interpolymer having
- i. a melt index of from 0.5 to 500 grams/10 minutes, and
- ii. a density which is at least 0.01 grams/centimeters3 greater than the density of the first polymer.
