摘要:
The invention relates to water-dispersible or water-soluble polymer powder compositions which can be crosslinked or condensed by acid and comprisesI) one or more pulverulent water-dispersible or water-soluble copolymers which can be crosslinked or condensed by acid,II) one or more pulverulent water-dispersible or water-soluble compounds from the group consisting of alkali metal or ammonium peroxo acid salts, andIII) one or more pulverulent water-dispersible or water-soluble reducing agents.
摘要:
Redispersible polymer powders which are cationically stabilized by spray drying a polymer dispersion with a cationic polymer can be used in higher concentrations in chemical building construction materials without introducing adverse properties.
摘要:
Copolymers of ethylene and vinyl chloride also containing a protective colloid, optionally in conjunction with a fatty acid compound or precursor thereof or with an organosilicon compound, can be employed to increase the water repellency of hydraulically settable construction materials.
摘要:
Water-redispersible polymer powder compositions based on homopolymers or copolymers of one or more monomers from the group consisting of vinyl esters of unbranched or branched alkylcarboxylic acids having from 1 to 15 carbon atoms, methacrylic esters and acrylic esters of alcohols having from 1 to 15 carbon atoms, vinylaromatics, olefins, dienes and vinyl halides, one or more protective colloids, if desired antiblocking agents, contain one or more compounds from the group of pozzolanas. The pozzolanic compounds preferably take the place of anti-blocking agents conventionally used.
