摘要:
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.

The present invention is directed to a dienophile-modified fatty acid composition and adhesive. The composition comprises a) a polycondensate of a1) a dimer of a fatty alcohol and/or a dimer of a fatty amine, and a2) a dimer of a fatty acid, said polycondensate having a weight average molecular weight of from 2,000 to 50,000 g/mol, and
b) a fatty acid derivative as a cross-linking agent, wherein said fatty acid derivative is obtainable by reacting b1) a fatty acid ester comprising at least two double bonds, and b2) a dienophile comprising at least one functional group selected from a carboxylic acid, a carboxylic acid ester and a carboxylic acid anhydride,
wherein the polycondensate and the cross-linking agent are capable of reacting with each other.
摘要:
The invention concerns an adhesive tape for flying reel changes having a backing layer (1) and adhesive layers (2,3) coated on both sides of said backing layer. The adhesive tape has a cleavage means (4) provided substantially transverse to at least said backing layer (1), thereby dividing said backing layer into a first portion (1a) and a second portion (1b), wherein the one adhesive layer is not effective in the area of the second portion (1b) and the other adhesive layer is not effective in the area of the first portion (1a).
摘要:
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.
摘要:
To provide a heat-expandable removable pressure-sensitive adhesive tape that maintains a high normal adhesive strength during bonding as well as can be readily separated or debonded by heat for separation or debonding even after the storage or use for a long time, regardless of an adherend type. 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.
摘要:
The present invention is directed to a pressure sensitive adhesive obtainable by reacting a) a polycondensate obtainable from a1) a furan derivative and a2) a dimer of a fatty alcohol, a dimer of a fatty acid and/or ester thereof, a dimer of a fatty amine, and/or a dimer of a fatty isocyanate; wherein the polycondensate has a Tg between -50°C and 0°C; and b) a cross-linking agent having at least 2 functional groups per molecule. The invention is also directed to a method for preparing the adhesive and to the use of the adhesive for laminating a sheet or film.
摘要:
The present invention relates to an 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 at least one blocked isocyanate compound, 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.
