摘要:
Disclosed is a method for destroying microorganisms in aqueous technical systems or products for water-based technical applications by adding 0.001 to 5 percent by weight of a water-soluble or water-dispersible polymer containing 30 to 100 molar percent of styrene sulfonic acid, 0 to 40 molar percent of an N-vinyllactam and/or N-vinylamine, and 0 to 30 molar percent of additional radically polymerizable monomers as a biocidal additive. Also disclosed is a method for protecting objects by applying an antimicrobially active aqueous composition comprising such an additive.
摘要:
The present invention relates to an ampholytic copolymer based on quaternized nitrogen-containing monomers, which has a molar excess of cationogenic/cationic groups over anionogenic/anionic groups, to cosmetic or pharmaceutical compositions which comprise at least one such ampholytic copolymer, and to further uses of these copolymers.
摘要:
Disclosed are vinyl lactam copolymers that are modified with polyalkylene oxide side chains, the use thereof as solubilizers for substances that are difficult to dissolve in water, and preparations containing such copolymers.

摘要:
The utilization of copolymers obtained by means of radically initiated copolymerization of a) 80 to 99,5% vinyl acetate by weight and b) 0,5 to 20% by weight of a sulfonate group-carrying, mono-olefinically unsaturated monomer, as solubilizers for substances with low solubility in water.
摘要:
The invention relates to the use of copolymers obtained by radically polymerising a mixture of: i) 30-80 % by weight N-vinyllactam, ii) 10-50 % by weight vinylacetate, and iii) 10-50 % by weight polyether, wherein the sum of the components i), ii) and iii) is equal to 100 % by weight as solubilisers for poorly water-soluble substances.
