    摘要: A composition of matter comprising a water-swellable IPN or semi-IPN including a hydrophobic thermoset or thermoplastic polymer and an ionic polymer, articles made from such composition and methods of using such articles. The invention also includes a process for producing a water-swellable IPN or semi-IPN from a hydrophobic thermoset or thermoplastic polymer including the steps of placing an ionizable monomer solution in contact with a solid form of the hydrophobic thermoset or thermoplastic polymer; diffusing the ionizable monomer solution into the hydrophobic thermoset or thermoplastic polymer; and polymerizing the ionizable monomers to form a ionic polymer inside the hydrophobic thermoset or thermoplastic polymer, thereby forming the IPN or semi-IPN.

    摘要: Presently described are optical stacks comprising a first optical film comprising a plurality of structures comprising an optically active portion designed primarily to provide optical gain and optionally an optically in-active bonding portion disposed on a first surface bonded to a second optical film with a light-transmissive adhesive layer such that a portion of the structures penetrate the adhesive layer and a separation is provided between the adhesive layer and the first surface. In one embodiment, the optical stacks exhibit a combination of high peel strength and high retained brightness, particularly after aging. The adhesive layer preferably comprises an interpenetrating network of the reaction product of a polyacrylate component and a polymerizable monomer and the adhesive layer has an elastic modulus ranging from 100 to 2000 MPa at 25° C.
