| abstract |
A composition comprises two or more ethylene copolymers, including a grafted ethylene copolymer; a tackifier, and two or more styrene polymers. The styrene polymers comprise an ABA block copolymer and one or both of a high impact polystyrene and an AB block copolymer. The composition may be used as an adhesive or tie layer. In particular, the composition may used to adhere articles comprising polystyrene, preferably to other articles comprising more polar materials, such as copolymers of ethylene and vinyl alcohol (EVOH), for example. |
