Pressure sensitive adhesives comprising a linear block copolymer having a rubbery block and at least one glassy block; a multi-arm block copolymer having at least three arms, each having both a rubbery block and a glassy block; a first high glass transition temperature tackifier compatible with the rubbery blocks; a second high glass transition temperature tackifier having compatible with the glassy blocks; and at least one of a low Tg tackifier, a plasticizer, and combinations thereof, are disclosed. Tapes that include such adhesive, methods of making such tapes, and bonded composites using such adhesives and tapes are also disclosed.

Block copolymer blend adhesives with multiple tackifiers

A directly illuminated display unit includes a display panel and one or more light sources disposed behind the display panel. The light sources are capable of producing illumination light. A diffusive light diverting layer is disposed between the one or more light sources and the display panel. The light diverting layer comprises first light diverting elements disposed on one of a first side of the light diverting layer facing display panel and second light diverting elements disposed on a second side of the light diverting layer facing away from the display panel. The diffusive light diverting layer further comprises diffusing particles disposed within a polymeric matrix.

Back-lit displays with high illumination uniformity

Disclosed is a method for modifying a polymer by carrying out a thermally-induced reaction in a mixing apparatus having a high shear environment and devolatilization capabilities. Also disclosed are the resulting materials.

Process to modify polymeric materials and resulting compositions

A directly illuminated display unit has a display panel and one or more light sources disposed behind the display panel. A diffuser is disposed between the one or more light sources and the display panel, and a light diverting layer is disposed between the one or more light sources and the diffuser. The light diverting layer has a first light-diverting surface facing the one or more light sources and a second light diverting surface facing the display panel. The light diverting layer diverts light passing from the one or more light sources to the diffuser, thus improving the uniformity of the light in the display unit.

A mixture of layered silicate, block copolymer having at least one block that is compatible with the first layered silicate, and a solvent is sheared while the solvent is removed.

Method of making a composition and nanocomposites therefrom

A composition comprising exfoliated silicate platelets; a thermoplastic polymer; and a block copolymer and method of making the same.

Nanocomposite and method of making the same

A directly illuminated display unit has a display panel and one or more light sources disposed behind the display panel. A diffuser is disposed between the light source unit and the display panel and a light diverting layer is disposed between the one or more light sources and the diffuser. The light diverting layer has light diverting members on a first side of the light diverting layer facing the diffuser. Surfaces of the light diverting members are disposed at more than one angle relative to a normal to the light diverting layer and also include one or more sharp changes of surface slope. The light diverting members spread the illumination light so as to be more uniform. Different light diverting members can have different apex angles. Also, different sides of a light diverting member can have best fit centers of curvature that are non-coincident.

A composition comprising a fluorinated block copolymer and at least one of an intercalated layered silicate or exfoliated silicate platelets, and methods of making the same.

Composition and method of making the same

A method of continuous polymerization using differential radial stirring is provided. Particularly suited for this method is a stirred tube reactor with a plurality of collinear stirring shafts that may rotate independently.

Stirred tube reactor and method of using the same

A stirred tube reactor has a plurality of collinear stirring shafts that may rotate independently.

Disclosed are block copolymers and end-functionalized polymers containing in their backbones at least one fluoro alkyl (meth)acrylate mer unit comprising &#x2014;CF, &#x2014;CF, or &#x2014;CF.

Fluorinated polymers

Pressure sensitive adhesive compositions and pressure sensitive adhesive articles containing the adhesive compositions are disclosed. The adhesive compositions of the invention generally demonstrate favorable cohesive strength at elevated temperatures. The adhesive compositions contain an acrylic acid ester copolymer having pendant styrenic polymeric moieties mixed with a polyarylene oxide polymer. The adhesive composition may be a foam.
