摘要:
The invention relates to double-sided adhesive tape comprising a viscoelastic, first polymer layer, a second polymer layer on the top face and a third polymer layer on the bottom face of the viscoelastic, first polymer layer, where the viscoelastic, first polymer layer is based on a polymer which is obtainable by polymerization of a monomer composition of 65% to 97% by weight of ethylhexyl acrylate and/or butyl acrylate, 0% to 30% by weight of methyl acrylate, 3% to 15% by weight of acrylic acid, the viscoelastic interlayer being crosslinked, the second polymer layer is based on a polymer which is obtainable by polymerization of a monomer composition of 85% to 95% by weight of ethylhexyl acrylate and/or butyl acrylate, 5% to 15% by weight of acrylic acid, this second polymer layer being thermally crosslinked using at least one epoxycyclohexyl derivative in the absence of accelerators.

A method of providing to a fragrance application a musky odor, comprising the addition thereto of at least one compound according to the formula I in which R1 is selected from H and CH3; R2, R3 are selected from the possibilities that (a) both are CH3; and (b) R2 and R3 together form a single bond (as indicated by the broken line); and n is an integer selected from 1, 2, 3, and 4. The compounds are useful in the complete range of fine and functional fragrance applications.

With a method configured to generate process gas that contains hydrogen sulfide and sulfur dioxide for the Claus process, hydrogen-sulfide containing feed gas is burned with pure oxygen by means of several burners opening out into a combustion chamber wherein the pure oxygen is fed into the combustion chamber through a central tube each, the feed gas through a tube arranged coaxially around the central tube and inert gas as purge gas via an annular duct coaxially surrounding the feed gas tube. A favorable option of the method consists in the use of CO2 reclaimed by desorption of laden methanol as purge gas.

Sealable, thermoformable, heat-shrinkable multi-layer film having a symmetrical construction around a two-ply inner layer, and having a heat shrinkability in machine direction and in cross direction of in each case at least 20% at 93° C., the heat-shrinkability being substantially unaffected by thermoforming, and use thereof with specially equipped packaging machines.
摘要:
A contact transparent single layer or multilayer film absorbing and/or reflecting UV radiation and short-wavelength visible light is disclosed. The film comprises at least one layer based on at least one optionally modified thermoplastic olefin homo- or co-polymer, comprising a combination of at least one organic or inorganic colored pigment or dye absorbing and/or reflecting short-wavelength visible light, and of at least one organic or inorganic compound absorbing and/or reflecting the UV radiation. The film disclosed herein can be used as a protective film against the effects of UV radiation and short-wavelength visible light, and a sewer cleaning system comprising said multilayer film as an external hose film and an inner, multilayer plastic film, and an impregnated UV-curable carrier material present between the two hose films.
摘要:
The present invention relates to a method to electroplate or electropolish a metal on a substrate wherein an ionic liquid is selected from the group of N+R1R2R3R4 X− or N+R5R6R7R8 Y− is employed as electrolyte, and a metal salt added to the ionic liquid is employed as the metal source or a metal anode is used as the metal source, wherein any one of R1 to R8 independently represents a hydrogen, alkyl, cycloalkyl, aryl, or aralkyl group that may be substituted with a group selected from OH, Cl, Br, F, I, phenyl, NH2, CN, NO2, COOR9, CHO, COR9, or OR9, at least one of R5 to R8 is a fatty alkyl chain, and one or more of R5 to R8 can be a (poly)oxyalkylene group wherein the alkylene is a C1 to C4 alkylene and the total number of oxyalkylene units can be from 1 to 50 oxyalkylene units, and at least one of R1 to R8 is a C1 to C4 alkyl chain, R9 is an alkyl or cycloalkyl group, X− is an anion having an N-acyl sulphonylimide anion (—CO—N−—SO2—) functionality, Y− is an anion compatible with the N+R5R6R7R8 ammonium cation, such as a halogenide anion, a carboxylate anion, a sulphate (both organic and inorganic sulphate), sulphonate, carbonate, nitrate, nitrite, thiocyanate, hydroxide, or sulphonylimide anion.
