Abstract: A process for the preparation of 2,2,5,5-tetramethyltetrahydrofuran (TMTHF) includes contacting a TMTHF precursor with a solid catalyst, where the TMTHF precursor is 2,5-dimethylhexane-2,5-diol and/or 2,5-dimethyl-4-hexen-2-ol, and where the solid catalyst is a beta zeolite. TMTHF produced by the process may be used as a solvent.

Abstract: Provided is a surface protection sheet that is less susceptible to breaking and tearing caused by adherend processing and can be easily removed from the adherend. The surface protection sheet comprises a substrate and a PSA layer placed on one face of the substrate. The base polymer of the PSA layer has a glass transition temperature of ?50° C. or higher. The surface protection sheet has at least 200% elongation at break in both the machine direction and the transverse direction.

Abstract: The present invention relates to a method for prevention of premature polymerization during the preparation, purification, transportation and storage of a polymerizable compound with at least one conjugated unsaturated group in the presence of an azine dye-based compound as inhibitor. Further the present invention relates to methods of preparing such inhibitors as well as to the inhibitors itself, as well as to methods of improving solubility and stability of dissolved inhibitors.

Abstract: The present invention provides pressure-sensitive adhesive films with a favourable visual appearance and surface printability without discoloration and burrs on the cutting edge after short-wavelength laser machining. At the same time, the PSA films of the present invention exhibit a favourable cuttability, allowing for high fiber laser as well as carbon dioxide laser cutting speeds. Since the use of the PSA films of the present invention as surface protecting films does not require extensive cleaning and polishing operations after the cutting process and the cutting process itself may be accelerated, the efficiency of laser machining methods may be improved.

Abstract: The present invention refers to a thermally debondable tape having a base adhesive layer and at least one thermally releasable adhesive layer including an adhesive and thermally expandable particles. The debondability even after long term storage or use shall be enhanced. In this regard the base adhesive layer has a lower adhesion at expansion temperature of the thermally expandable particles than at room temperature.

Abstract: A polyvinyl chloride-based adhesive tape or sheet has a base material layer formed to include 10 to 40 parts by weight of plasticizing agent(s) in relation to 100 parts by weight of a polyvinyl chloride-based resin and an adhesive layer on one surface of the base material layer, the plasticizing agent includes at least one type of plasticizing agent having an SP value of at least 9.0.

Abstract: The heat-expandable removable pressure-sensitive adhesive tape of the present invention includes at least a blowing agent-containing pressure-sensitive adhesive layer A, a microparticle-containing viscoelastic substrate B, a peelable or peel-assisting film layer C, and a pressure-sensitive adhesive layer D. A multilayer structure containing at least the peelable or peel-assisting film layer C and the pressure-sensitive adhesive layer D is arranged on at least one side of the blowing agent-containing pressure-sensitive adhesive layer A where the blowing agent-containing pressure-sensitive adhesive layer A is in direct contact with the peelable or peel-assisting film layer C. The peelable or peel-assisting film layer C can be removed from the blowing agent-containing pressure-sensitive adhesive layer A by heat treatment after storage in an atmosphere of 75° C. for 8 weeks.

Abstract: An object of the present invention is to provide a heat-expandable/peelable acrylic pressure-sensitive adhesive tape that maintains a high adhesion force, and can be easily separated or debonded at the bonded part by heating, regardless of the material constituting the adherend. Disclosed is a heat-expandable/peelable acrylic pressure-sensitive adhesive tape or sheet which includes at least a pressure-sensitive adhesive layer containing a blowing agent, a peelable or peel-assisting film layer, and a viscoelastic substrate containing microparticles, in which at least the peelable or peel-assisting film layer and the microparticle-containing viscoelastic substrate constitute a multilayer structure, and the multilayer structure is arranged on or above at least one side of the pressure-sensitive adhesive layer so that the blowing agent-containing pressure-sensitive adhesive layer is in contact with the peelable or peel-assisting film layer with or without the interposition of another layer.

Abstract: The present invention relates to an adhesive tape, a method of manufacturing thereof and to uses thereof. More specifically, the present invention relates to an adhesive tape that can be used as such in order to join two entities with their respective surfaces together and/or to attach an entity on the surface of a substrate, whilst the peel adhesion is reduced, i.e. the tape can be removed easily, if desired. The adhesive tape comprising: a layer of a thermally shrinkable polymer, said layer having two surfaces opposite each other, a layer of a pressure sensitive adhesive composition on one of said two surfaces, said pressure sensitive adhesive composition comprising an amorphous polymer, thermally expandable particles and/or at least one blocked isocyanate compound.
