摘要： The present invention relates to a multilayer structure, such as a film or a sheet, and articles made from such multilayer structures. The present invention provides a multilayer structure comprising at least three different layers A, B and C, wherein said layer B is disposed between said layer A and said layer C and is capable of binding said layer A to said layer C, wherein layer A comprises a polylactide (PLA) polymer, layer B comprises a lactide-rich poly(lactide- co-glycolide) (PLGA) polymer, and layer C comprises a polyglycolide (PGA) polymer and/or a glycolide-rich poly(lactide-co-glycolide) (PLGA) polymer. The present invention also provides a multilayer structure comprising at least one barrier layer, providing gas barrier properties, wherein said barrier layer comprises a glycolide-rich poly(lactide-co-glycolide) (PLGA) polymer.

摘要： An elastomeric composition, including at least one skin layer and a core layer, with non-blocking properties such that the elastomeric composition can be wound is provided. The core layer includes an elastomer, and the skin layer includes an elastomer, which may be the same or different from the core layer, and a non-elastic polyolefin. Further, the skin layer can be present as a small portion of the total elastomeric composition, and may maintain the elastic efficiency of the composition.

摘要： A primer coating composition for bonding a functional laminate to a lens during cast-polymerization, including an acrylic polymer; a urethane acrylate oligomer; a reactive component capable of reacting with a lens-casting monomer for casting the cast-polymerized lens, a UV initiator or a thermal initiator, and a solvent. A method for cast-polymerizing a lens, including applying the primer coating composition to at least one external surface of a functional laminate; cutting and forming the functional laminate, placing the shaped functional laminate to which the primer coating is applied and a monomer for casting a lens in a casting cell so that the monomer contacts the primed surface of the functional laminate, and cast-polymerizing the monomer in the casting cell. An ophthalmic lens, including a cast-polymerized lens including at least one polymer, a functional laminate, and a primer coating obtained by curing the primer coating composition and deposited on at least one external surface of the functional laminate.

摘要： The present invention relates to an acrylic multilayer foil comprising at least one layer in which silica particles are uniformly distributed in an acrylic polymer matrix and at least one further layer. Due to adhesive promoting properties of the layer comprising silica particles, the multilayer foil can be easily coated or laminated onto a substrate. The foil has a high weathering resistance and excellent mechanical properties. Therefore, the multilayer foil of the present invention is highly suitable for surface-protection of materials such as polyvinyl chloride (PVC) and for use in high-pressure laminates (HPLs).
