Optically clear adhesive compositions contain an elastomeric polymer and a low molecular weight polymeric additive. The elastomeric polymer and the low molecular weight polymeric additive form an acid-base interaction. The refractive index of the adhesive composition is higher than the refractive index of the elastomeric polymer. The adhesive composition may also contain additional domains of liquids, polymers, additives or particles that have a higher refractive index than the elastomeric polymer.

Optically clear high refractive index adhesives

A polymerizable pre-adhesive composition includes packaging material and a packaged pre-adhesive reactive mixture sealed within the packaging material. The packaging material includes: a semicrystalline polylactic acid (PLA); a polyvinyl acetate (PVAc); and a plasticizer; wherein the PLA/PVAc-containing packaging material has a single Tof less than 25&#xb0; C. and a normalized Haze value of less than 10% per 25 microns.

Packaged pre-adhesive composition including a polylactic acid-containing packaging material, adhesives, and articles

Adhesive compositions that are optically transparent include a (meth)acrylate-based copolymer having a refractive index of at least 1.48, and particles of a thermoplastic polymer. At least some of the particles have an average particle size that is larger than the wavelength of visible light. The adhesive compositions are prepared by hot melt processing packaged adhesive compositions.

Optically clear hot melt processable high refractive index adhesives

This disclosure provides (meth)acryloyl pressure-sensitive adhesive foams and foam articles having one or more of the following properties: small cells, uniform cell sizes, pressure sensitive adhesive compositions, compliance to irregular substrates and vibration damping, and shock absorbing properties.

(Meth)acryloyl pressure-sensitive foam adhesives

Packaged viscoelastic compositions comprising viscoelastic copolymers and a packaging material are disclosed. The viscoelastic copolymers are urea copolymers, which are the reaction product of polyisocyanates and polyamines. The packaged viscoelastic compositions are hot melt processable.
