    摘要： The present invention relates to compositions which are suitable for optimizing mineral building material compositions so that the flow behaviour and the deaeration of the compositions is positively influenced, as a result of which very smooth, virtually pore-free surfaces can be achieved. The compositions can consist of a mixture or comprise a mixture which contains at least one component (a) which comprises a compound N which displays a wetting action in aqueous cement-containing binder systems and contains at least one further component (b) which comprises a compound E which has antifoam properties in aqueous cement-containing binder systems. The compound N in component a) can preferably be a nonionic or amphoteric surfactant, preferably an alkyl alkoxylate or a betaine. The compound E in component b) can preferably be a polyetherpolysiloxane on a support material.

    摘要： A process is described for recycling superabsorbent polymer fines into a process that includes treating the superabsorbent polymer fines with caustic and a polymerization step for making the superabsorbent polymer gel. The process requires treating the superabsorbent polymer fines with a caustic, followed by mixture with polymerizable monomer solution, and polymerizing the mixture of the superabsorbent polymer fines and monomer to form the aqueous fluid absorbent polymer. In the process, the fines are incorporated into the new polymer gel and become indistinguishable there from. The gel may then be comminuted into a particulate dried and then separated into a portion having a desired minimum particle size in a fines portion having less than the desired size. The particulate may then be coated with a surface crosslinking agent and surface additives and heated for surface conversion.
