摘要:
The use of an aqueous polyurethane dispersion adhesive is described for producing biodisintegratable composite foils where at least two substrates are adhesive-bonded to one another with use of the polyurethane dispersion adhesive, where at least one of the substrates is a biodisintegrable polymer foil. At least 60% by weight of the polyurethane is composed of diisocyanates, polyesterdiols, and at least one bifunctional carboxylic acid selected from dihydroxycarboxylic acids and diaminocarboxylic acids.
摘要:
A method for producing biodisintegratable composite foils with an aqueous polyurethane dispersion adhesive. The method involves adhesive-bonding a first substrate to a second substrate with use of the aqueous polyurethane dispersion adhesive. At least one of the first substrate and the second substrate is made of a biodisintegratable polymer foil, and at least 60% by weight of the polyurethane contains diisocyanates, polyesterdiols, and bifunctional carboxylic acids. The bifunctional carboxylic acids are dihydroxycarboxylic acids or diaminocarboxylic acids.
摘要:
A description is given of an aqueous polymer dispersion comprising at least one polyurethane, dispersed in aqueous phase and having one or more uretdione groups, and at least one solid polyamine with a deactivated surface, said dispersion being useful as an adhesive, coating material or sealant or for producing adhesive, coating or sealing compositions. The compositions can be activated thermally or by electromagnetic radiation.
摘要:
The methods and compositions of the present invention are directed to coloration of anagenic hair. The methods involve priming and deep cleaning the anagenic hair followed by coating the hair strands with a composite pigment containing film of a small molecule and a film forming composition which covalently interact to form an intimate three dimensional silicone network incorporating the pigment on the surfaces of the hair.

An aqueous acidic polymerization liquid comprising polymerizable monomers or oligomers with carboxylate and/or carboxylic acid moiety or moieties, and basal surface modified clay that is homogenously dispersable in said liquid is provided, and also methods for making such liquids, and also surface-modified-clay linked water-absorbing polymers made with said liquids and methods, and disposable absorbent articles comprising such surface-modified-clay linked water-absorbing polycarboxylate/polycarboxylic acid polymers.
摘要:
Absorbent structures, and absorbent articles with such structures, comprising water-absorbing polymer having a coating of film-forming polyurethane and therein incorporated a hydrophilic silica.
摘要:
The invention relates to a process for producing a water-absorbing material by coating water-absorbing polymer particles with a film-forming polyurethane and silica, heat treating the coated particles and coating the heat-treated particles with pyrogenic hydrophilic silica. The invention further relates to the water-absorbing material obtainable according to the process of the invention. The water-absorbing material has improved wicking ability (FHA) and core shell saline flow conductivity (CS-SFC).
摘要:
A method and a device for simplifying the forming of game parties in wireless communication networks is provided. A game directory is generated comprising all available (multi-player) games on a mobile device and exchanging said information between different gaming devices. Said game directory is generated by querying a memory accessible by said electronic gaming device for electronic games available for execution on, and generating a game directory having entries for each electronic game which is determined. Said game directory is then exchanged to visualize all available games to all potential game partners.
摘要:
An absorbent layer containing water-absorbing polymeric particles that are surface-treated and that are immobilized by a matrix, formed from a thermoplastic adhesive component, including a thermoplastic polymers and a specific plasticizer, and being free of low weight average molecular weight (e.g. below 1000, or below 2000 or even below 3000 g/mole) tackifiers and plasticizers. The absorbent articles may for example be adult incontinence articles, infant (e.g. baby, toddler) diapers, including training pants, and feminine hygiene articles, such as sanitary napkins.
摘要:
Superabsorbent polymer particles, coated with a block copolymer comprising at least four blocks being at least two hard blocks, one soft block and one hydrophilic block, wherein a the soft block is sandwiched between the hard blocks.
