    Abstract: The present invention relates to a pressure sensitive adhesive foam with a percentage of theoretical density less than 90, wherein the foam has a peel adhesion of greater than about 1 N/cm and a compression set under constant deflection of less than about 60 %. The present invention further includes a pressure sensitive adhesive foam comprising a thermoplastic block copolymer; a tackifying resin; an isocyanate terminated monomer or oligomer; a polymer comprising a backbone selected from the group consisting of polybutadiene, polyester and polyether, wherein the polymer contains at least 2 active hydrogens capable of reacting with the isocyanate terminated monomer; and expandable particulate materials. The present invention further includes a pressure sensitive adhesive foam comprising a thermoplastic olefin polymer or copolymer, having a density less than 0,91 g/cm and a torsion modulus less than 18 MPa, and a tackifying resin; and, optionally, plasticizing oil and expandable particulate materials, or glass microspheres. The invention finally further comprises a method of forming the above film.

    Abstract: The present invention is a film formed from an acrylate blend. The preferred blend is a film comprising components (a and b), component (a) being an ethylene butyl acrylate copolymer (EBAC) which is less than about 95 percent by weight of a total weight of components (a and b), wherein the EBAC has a content of acrylate groups from about 8 to about 36 percent by weight of the total weight of the EBAC; and component (b) being an ethylene methyl acrylate copolymer (EMAC) which is greater than about 5 percent by weight of the total weight of components (a and b), wherein the EMAC has a content of acrylate groups from about 8 to about 42 percent by weight of the total weight of the EMAC. The invention further includes a process for manufacturing this film for use as an interlayer in laminates comprising the steps of mixing the melt of thermoplastic polymer resins to form an ethylene butyl acrylate/ethylene methyl acrylate blend and forming the ethylene butyl acrylate/ethylene methyl acrylate blend of thermoplastic resins into a film for use as an interlayer in laminates. The invention still further includes a laminate comprising at least two sheets and at least one interlayer, the interlayer(s) being in between the sheets and wherein the interlayer is comprised of the film described above. The invention still further includes a laminate comprising an acrylate film laminated between two laminae wherein the film and the laminate have properties similar to PVB and laminates made with PVB, respectively.
