摘要:
The invention relates to a radiation crosslinkable hot melt pressure sensitive adhesive comprised of a radiation crosslinkable polymer as component (A) based on epoxidized polyoflefins, wherein the epoxy groups are not consolidated in blocks; a tackifying resin possessing no epoxy groups as component (B); optionally a low molecular weight oligomer as component (C) that possesses reactive groups that can react with the epoxy groups of component (A); and an additive comprising a photo initiator as component (D).
摘要:
A method of dispatching a plurality of physical objects is provided. The method includes associating a delivery address with physical objects; determining a sequence of delivery for the physical objects; and determining a transport area for the physical objects, the transport area includes at least one transport location. The physical objects are collected and jointly transported according to the determined transport area. Prior to delivery, the delivery addresses are entered into a data storage unit in a transportation vehicle in accordance with the delivery sequence. A navigation system aboard the transportation vehicle determines a route-optimized itinerary for delivering the physical objects.
摘要:
A process for the production of a polyurethane hot-melt adhesive based on grafted polyester-polyether block copolymers with grafted-on hydroxyl groups and the reaction thereof with a stoichiometric excess of a polyisocyanate and the optional mixing thereof with further pre-polymers based on polyether polyols and polyester polyols is disclosed. By this process, the polyester-polyether block copolymers are firmly incorporated into the polyurethane matrix on curing, so that they are migration-proof. Highly-elastic hot-melt adhesives result, which, with optional foaming, are also suitable for the production of elastic seals.

摘要:
The invention relates to a copolymer which can be obtained by radical copolymerisation of at least two components A and B. According to the invention, a) at least one ester of one at least difunctional carboxylic acid which has at least one olefinically unsaturated double bond is used with an alkyl oxide addition compound as component A and b) at least one additional monomer which can be subjected to radical polymerisation is used as component B. The invention also relates to a method for producing copolymers of this type and to the use thereof, in particular, to their use as a binding agent in adhesives.
摘要:
Lignin sulfonates may be used (i) in a liquid multiphase cleaning composition with at least two continuous phases which contains at least one aqueous phase I and a non-aqueous liquid phase II immiscible with this aqueous phase and which can be temporarily converted into an emulsion by shaking, (ii) in a composition for cleaning hard surfaces to reduce the rain effect and/or the film effect and (iii) in a process for reducing the rain effect and/or the film effect on a hard surface treated with a liquid cleaning composition, the surface being treated with a liquid cleaning composition in concentrated or diluted form containing at least one lignin sulfonate and (iv) in a process for cleaning hard surfaces, more particularly glass, in which a cleaning composition according to (i) is temporarily converted into an emulsion by shaking, applied to the surface to be cleaned, preferably by spraying, in quantities of 1.5 to 10 g per m2 and the surface is then optionally cleaned by wiping with a soft absorbent material.
摘要:
The process of curing a radical-polymerizable multicomponent mixture containing an olefinically-unsaturated compound with ambient air by adding to the mixture an alkyl, cycloalkyl or aryl hydrazone of an aliphatic, cycloaliphatic or aromatic aldehyde or ketone which forms a hydroperoxide as an initiator for curing the mixture.
摘要:
In order to decrease the amount of time required to localize a structure of interest and generate a diagnostic image, a target point is identified within a volume represented by a 3D dataset. The target point is based on a first user input. The 3D dataset is scaled around the identified target point to identify a volume of interest within the 3D dataset, where the scale is based on one or more second user inputs. The 3D dataset is automatically cropped to the volume of interest based on the scaling, and a representation of the cropped 3D dataset is displayed.
摘要:
The invention relates to a controlled polymerization method for producing ABA-triblock copolymers on the basis of (meth)acrylate with A-blocks having a narrow, monomodal molecular weight distribution, and a B-block having a wide, monomodal molecular weight distribution. The invention further relates to the use thereof as binders in glues or sealing compounds.
摘要:
The invention relates to a controlled polymerization process for preparing (meth)acrylate-based AB diblock copolymers with a B block which has a narrow monomodal molecular weight distribution, and an A block which has a broad monomodal molecular weight distribution, and to the use thereof, for example, as a binder in adhesives or sealants.
