摘要:
The use of a composition of low or no tack at 20° C. as an adhesive that can be adhered to itself (referred to below for short as an autoadhesive).
摘要:
A double-sidedly coated backing comprising on one side (referred to below as face) an outer layer of a pressure-sensitive adhesive and on the other side (referred to below as reverse) an outer layer of an apolar release coating forming a contact angle of greater than 85° with water at 20° C.

A description is given of a sound deadener composition comprising a polymer dispersion comprising (a) at least one water-dispersed polymer obtainable by emulsion polymerization of free-radically polymerizable monomers and having a glass transition temperature in the range from −60 to +60° C.; (b) inorganic fillers; and (c) at least one fluorinated compound selected from perfluoroalkyl-substituted carboxylic acids and their salts, fluorocarbon resins, surface-active, fluoroaliphatic polymeric esters, and fluorine-containing, acrylate-based copolymers. A description is also given of a method for damping oscillations or vibrations of components of vehicles and machines, using the sound deadener composition of the invention.
摘要:
A description is given of the use of a polymer dispersion for preparing sound deadener compositions, the polymer dispersion being obtainable by emulsion polymerization of free-radically polymerizable monomers in the presence of at least one protective colloid which is an amphiphilic graft copolymer. Preferred protective colloids have a polyalkylene oxide main chain and vinyl ester-comprising side chains. A description is also given of corresponding sound deadener compositions which comprise the polymer dispersion, and of a method for damping oscillations or vibrations of vehicle components.

摘要:
A coated polymer foil is described and can be produced via coating of a polymer foil with an aqueous composition comprising (A) a polymer which is obtained via free-radical polymerization and which is composed of from 10 to 80% by weight of a compound selected from ethylenically unsaturated anhydrides and ethylenically unsaturated dicarboxylic acids, the carboxylic acid groups of which can form an anhydride group, and (B) an alkanolamine having at least two hydroxy groups. The coating gives the polymer foil an oxygen barrier and can in particular be used for producing packaging.

摘要:
The invention relates to a system for producing conveyor belts having a rope core, for example a wire rope core, comprising at least one rope unwinding unit having a plurality of rope reels, from which the ropes to be embedded in the conveyor belt are unwound, a combining unit in which the ropes, which are under tensile stress and run in the longitudinal belt direction parallel to one another in one plane, are combined with one or more raw rubber webs to form a raw belt, and a vulcanization press in which the raw belt is vulcanized by means of pressure and/or heat forming the conveyor belt. Said system is characterized in that the rope unwinding unit is designed as a rope unwinding and tensioning unit, in which each rope is individually tensioned to the required production tension.

The use of polyelectrolyte complexes as plasticizer barrier is described, in particular those formed from anionic polymer and from cationic polymer, as also are plasticized substrates and production of the same, where the plasticized substrates have been coated with at least one layer which comprises at least one polyelectrolyte complex.
摘要:
The present invention relates to textile two- or three-dimensional structures formed from fibers and/or ribbons and swellable materials, the fibers and/or ribbons present in the structure and also the swellable materials each being present in such an amount that the fibers and/or ribbons are encased by the swellable materials and the voids in the structure are, in the swollen state, partially or completely filled by materially bound water and the swellable materials used being aqueous emulsions of (co)polymers of at least one ethylenically unsaturated monomer MON which are applied to the fibers and/or ribbons.
