摘要:
Cling articles comprise a cling backing a first heat-activatable adhesive in contact with at least a portion of a major surface of the cling backing. The heat-activatable adhesive has an activation temperature of at least about 40 degrees Celsius, and has a gel content at or above the activation temperature of at least about 5 percent.
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.
摘要:
Methods of applying a pressure sensitive adhesive to a substrate and adhering substrates together that includes applying a latent, over-tackified, adhesive to a substrate and applying a plasticizing agent to activate the latent, over-tackified, adhesive to form a pressure sensitive adhesive.
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:
Hardenable and hardened dental compositions that include thermally responsive additives, and articles including such hardenable and hardened compositions, are provided. Upon heating, the hardened compositions are useful for reducing the bond strengths of orthodontic appliances adhered to tooth structures with the hardened compositions.

摘要:
Polydiorganosiloxane polyoxamide, linear, block copolymers and methods of making the copolymers are provided. The method of making the copolymers involves reacting a diamine with a polydiorganosiloxane precursor having oxalylamino groups. The polydioroganosiloxane polyoxamide block copolymers are of the (AB)n type.
