Abstract:
The invention relates to a dispersion or solution of a polymer in water, organic solvents or mixtures thereof. The invention is characterised in that the polymer contains at least 0,001 mols of 3,4 dihydroxyphenyl groups (calculated at 109 g/mol) for 100 g polymer.
Abstract:
Process for bonding non ceramic floor coverings to a substrate, wherein an aqueous adhesive is used, which comprises a synthetic polymer as a binder and wherein the adhesive comprises hydrolyzable silane groups.
Abstract:
Adhesives (I), containing (a) 5-95 wt% adhesive dispersion with a viscosity of 2000-10,000 mPa.s which contains (a1) an aqueous polymer dispersion obtained by radical polymerisation of a mixture (M) containing ethylenically unsaturated monomer(s) (A) to a polymer (P) in presence of a protective colloid based on a water-soluble prepolymer of at least one water-soluble monomer (B) selected from alpha . beta -unsaturated 3-6C mono- or di-carboxylic acids, their anhydrides and half-esters and mixtures thereof, (a2) optionally a base, i.e. alkali metal hydroxide, ammonia or volatile amine, (a3) optionally a completely water-miscible organic solvent, and optionally other additives, (b) 0-90 wt% polysaccharide and/or protein and/or protein degradation product, (c) 0-95 wt% filler(s), (d) 0-10 wt% emulsifier(s), (e) 0-30 wt% other additives, and water to 100 wt%.
Abstract:
An aqueous composition comprises a mixture of from 10 to 50% by weight of a polymer A) having a gel content of less than 40% by weight and a number-average molecular weight M n of the soluble fractions of less than 30,000 and from 50 to 90% by weight of a filler B), the amounts by weight being based on the weight sum of the polymer and of the filler.
Abstract:
An aqueous composition is essentially free of organic solvents, plasticizers and additional tackifiers and contains water and 20-99% by weight of a polymer and 1-80% by weight of a filler, the percentages by weight being based on the sum of the components of the aqueous composition, with the exception of water.
