摘要:
Embodiments of the invention provide block composites comprising a soft copolymer, a hard polymer and a block copolymer having a soft segment and a hard segment, wherein the hard segment of the block copolymer is the same composition as the hard polymer in the block composite and the soft segment of the block copolymer is the same composition as the soft copolymer of the block composite and their use as impact modifiers.
摘要:
Embodiments of multilayer films are disclosed comprising a first layer comprising polyethylene, a second layer comprising a first medium density polyethylene; a barrier layer; a third layer comprising a second medium density polyethylene; and a fourth layer comprising polyethylene. The second layer may be positioned between the first layer and the barrier layer. The barrier layer may be positioned between the second layer and the third layer.
摘要:
The invention provides a film comprising at least two layers, a first layer and a second layer; and wherein the first layer is formed from a first composition comprising a polyester, a polylactic acid, or a combination thereof; and wherein the second layer is formed from a second composition comprising at least the following: A) functionalized ethylene-based polymer, and B) ethylene/alpha-olefin interpolymer; and wherein the first layer is adjacent to the second layer.
