摘要： Non-silicone urea-based adhesives are disclosed which are prepared by the polymerization of reactive oligomers with the general formula X—B—X, where X is an ethylenically unsaturated group and B is a unit free of silicone and containing urea groups. The reactive oligomers can be prepared from polyamines through chain extension reactions using diaryl carbonates followed by capping reactions. Adhesive articles, including optical adhesive articles may be prepared using the disclosed non-silicone urea-based adhesives.

摘要： Provided is a substrate for processing a wafer. The present invention can provide a substrate having excellent heat resistance and dimensional stability. The present invention can provide a substrate that has excellent stress relaxation properties, and therefore can prevent a wafer from being destroyed due to residual stress. Also, the present invention can provide a substrate that can prevent a wafer from being damaged or fried off due to a non-uniformly applied pressure during the wafer processing process, and that exhibits excellent cuttability. For these reasons, the substrate can be useful as a sheet for processing a wafer in various wafer preparation processes such as dicing, back-grinding, and picking-up.

摘要： The present invention discloses thiourea-containing dendrimers and thiourea-containing hyperbranched polymers, and respectively a preparation method for the thiourea-containing dendrimer and a preparation method for the thiourea-containing hyperbranched polymer, and a thiourea-containing dendrimer and a thiourea-containing hyperbranched polymer having increased water solubility prepared by using the thiourea-containing dendrimer and the thiourea-containing hyperbranched polymer as raw materials. Finally, disclosed are applications of the thiourea-containing dendrimers and the thiourea-containing hyperbranched polymers in the preparation of antitumor and antimicrobial drugs. The thiourea-containing dendrimer and the thiourea-containing hyperbranched polymer have a significant growth inhibitive effect on solid tumors and low toxicity to normal tissues, and thus can be used for preparing drugs for treating malignant tumors. The thiourea-containing dendrimer and the thiourea-containing hyperbranched polymer also have a good antimicrobial effect on various bacterial strains and thus can be used for preparing antiviral or antibacterial drugs.

摘要： Optically clear curable adhesive films that are heat conformable prior to setting include a reactive composition. The curable films are flexible and free-standing, and have a complex viscosity of greater than 100,000 poise (10,000 Pascal seconds) at 25° C. and less than 100 poise (10 Pascal seconds) at 85° C., prior to setting. The set film has an adhesive shear strength of greater than 100 Newtons per square centimeter (N/cm2) to a glass substrate when measured according to the Shear Adhesion Test Method. The reactive composition includes an ethylenically unsaturated polyester-containing oligomeric composition that is the reaction product of a saturated, amorphous co-polyester polyol and a compound with a terminal polyol-reactive group and a terminal ethylenically unsaturated group, a (meth)acrylate functional material, and at least one initiator.

摘要： The present invention relates to a back grinding sheet (BG sheet) (1a, 1b, 1c) having an unevenness-absorbing layer (12) on a substrate (11), in which the unevenness-absorbing layer is a layer formed of a film-forming composition containing (A) a urethane (meth)acrylate and (B) a polymerizable monomer except component (A) and the layer satisfies the following requirements (a) to (c): (a) a loss tangent at 70° C. measured at a frequency of 1 Hz is 1.5 or more, (b) a relaxation rate 300 seconds after a square (1 cm×1 cm) of the unevenness-absorbing layer is compressed at 25° C. and a compressive load of 10 N is 30% or less, and (c) a storage elastic modulus at 25° C. measured at a frequency of 1 Hz is 1.0 to 10.0 MPa. The BG sheet of the present invention has excellent absorptivity of uneven portions such as bumps in a semiconductor wafer and can suppress formation of gaps between bumps and the BG sheet and simultaneously suppress a phenomenon where the resin layer (unevenness-absorbing layer) of a BG sheet oozes from the edges of a roll when the BG sheet is wound up in the form of roll.
