摘要:
Radiation-curable, tackifier-free compositions are provided which contain: (i) a blend of certain acrylate esters and monoethylenically-unsaturated copolymerizable monomers; (ii) certain .alpha.-olefin polymers; and (iii) a photoinitiator and optionally, a crosslinker. Pressure-sensitive adhesives having good adhesion to both low and high energy surfaces as well as possessing excellent low and high temperature performance properties are prepared by exposing the radiation-curable compositions to light having a wavelength in the range of from about 280 to 400 nm.
摘要:
Acoustic sensors, preferably surface acoustic wave sensors, and more preferably shear horizontal surface acoustic wave sensors that include soluble mixed with oligomers and/or polymers formed from such monomers), or multifunctional compounds, for example, that can function as either waveguide materials, immobilization materials for secondary capture agents (e.g., antibodies), or both.
摘要:
Articles are provided that include an optical film and an optically clear pressure sensitive adhesive layer on at least one outer surface of the optical film. Additionally, articles are provided that include a pressure sensitive adhesive layer that resists bubble formation when adhered to an outgassing substrate. The pressure sensitive adhesive layer in the various articles contain a (meth)acrylate block copolymer.
摘要:
Heat-activatable adhesives comprise a semi-crystalline polymer. The semi-crystalline polymer comprises alkyl (meth)acrylate monomer units having an alkyl group that contains at least about 20 carbon atoms, alkyl (meth)acrylate monomer units having an alkyl group that contains from about 4 to about 12 carbon atoms, and optionally ethylenically-unsaturated non-acidic polar monomer units. Methods for making heat-activatable adhesives and articles therefrom are also included.
