Abstract:
A process for coating plastic or metal surfaces by treating the plastic or metal surface in question with an aqueous dispersion comprising (A) at least one ethylene copolymer having a molecular weight Mn in the range from 2000 to 20 000 g/mol, selected from those ethylene copolymers which contain, copolymerized as comonomers, (a) from 15.5 to 19.9% by weight of at least one ethylenically unsaturated C3-C10-carboxylic acid and (b) from 80.1 to 84.5% by weight of ethylene, (B) at least one base, in one step and subsequently providing the plastic or metal surface in question with at least one further layer in at least one further step.
Abstract:
The invention relates to a multi-layer finish on a substrate, containing at least one radiation-curable paint system (F) and at least one elastic intermediate layer (D) which is located between the substrate and the radiation-curable paint system (F) and has a maximum glass transition temperature (Tg) of -20 °C.
Abstract:
The invention relates to copolymers that contain, polymerized into them, as comonomers (a) ethylene, (b) one or more compounds of general formula (I), (c) optionally one or more alkenylphosphonic diesters, (d) optionally one or more additional radically copolymerizable comonomers, the variables being defined as follows: R1 is selected from hydrogen and unbranched or branched C1-C10 alkyl, R2 is selected from hydrogen and unbranched or branched C1-C10 alkyl, R3 is selected from hydrogen, phenyl, benzyl and unbranched or branched C1-C10 alkyl and unbranched or branched hydroxy-C2-C10 alkyl, as a free acid or partially or completely neutralized with alkali metal, alkaline earth metal, ammonia or organic amine.
Abstract:
The invention relates to a method for producing carboxylate-rich copolymers from monoethylenically unsaturated monocarboxylic and dicarboxylic acids having an average molecular weight Mw of at least 3000 g/mol and at least 20.1 % by weight of the dicarboxylic acid by radical polymerization in the presence of 2 to 19.9 molecular equivalents of an organic amine, based on the total amount of all COOH groups of the monocarboxylic and dicarboxylic acids at a temperature of not more than 130 °C. The invention also relates to carboxylate-rich copolymers which have a low neutralization degree and are obtained by the inventive method, and to the use of said copolymers for treating surfaces and as bonding agents for fiber bonding.
Abstract:
This invention relates to a process of producing compounds, which are useful as bleach boosters, as well as to the compounds, which are obtainable using said process, and to their use.
