Disclosed are compositions comprising at least one substantially random interpolymer of ethylene and a vinylidene aromatic monomer or a hindered aliphatic vinylidene monomer and optionally at least one C3-C20 α-olefin monomer, and at least one tackifier. The claimed compositions are useful in adhesives, such as are employed in various applications, such as in packaging and carton sealing, bookbinding, masking tape, clear office tape, labels, decals, bandages, decorative and protective sheets (such as shelf and drawer liners), floor tiles, sanitary napkin/incontinence device placement strips, sun control films, and the joining of gaskets to automobile windows. The claimed compositions further find use in a variety of applications, such as sealants, coatings, molded articles, and multilayered structures.
A composition comprising from 5 to 95 weight percent of at least one substantially random interpolymer of ethylene and a vinylidene aromatic monomer or a hindered aliphatic vinylidene monomer and optionally at least one C3-C20 α-olefin monomer, wherein the substantially random interpolymer comprises from 1-65 mole percent of the vinylidene aromatic monomer or hindered aliphatic vinylidene monomer, and from 5 to 95 weight percent of at least one tackifier.
An adhesive which comprises from 5 to 95 weight percent of at least one substantially random interpolymer of ethylene and a vinylidene aromatic monomer or a hindered aliphatic vinylidene monomer and optionally at least one C3-C20 α-olefin monomer, wherein the substantially random interpolymer comprises from 1-65 mole percent of the vinylidene aromatic monomer or hindered aliphatic vinylidene monomer, and wherein the adhesive further comprises from 95 to 5 weight percent of at least one second component selected from the group consisting of tackifiers, waxes, homogeneous linear or substantially linear ethylene/α-olefin interpolymers, ultra-low molecular weight ethylene polymers, processing aids, and mixtures thereof.
A coextruded or laminated multilayer film, in which at least one layer comprises an adhesive comprising at least one substantially random interpolymer of ethylene and a vinylidene aromatic monomer or a hindered aliphatic vinylidene monomer and optionally at least one C3-C20 α-olefin monomer.
The coextruded or laminated multilayer film of claim 16 in which the adhesive is adhered to a metal foil.
A tape comprising a substrate to which has been applied an adhesive comprising:
