摘要： Process for preparing water-soluble polymers in powder form by polymerization of water-soluble monoethylenically unsaturated monomers comprising the successive steps: a) Spraying on the inner wall of a polymerization vessel, the lubricant composition LC1: alkyl oleate/polyoxyethylene oleyl ether phosphate/sorbitan monolaurate, b) Polymerizing in aqueous solution in the presence of polymerization initiators at least one water-soluble monounsaturated ethylenic monomer, c) Discharging the polymer gel, d) Granulating the polymer gel thus obtained in a granulator, in presence of a lubricant composition LC2: alkyl oleate/polyxoyethylene oleyl ether phosphate/sorbitan monol aurate, e) Drying the polymer gel to obtain a polymer in powder form, f) Grinding and sifting the powder.

摘要： The invention relates to a new dialkyl tin oxide catalyst composition and its use for the synthesis of amino alkyl (meth)acrylates by transesterification from an alkyl (meth)acrylates and an amino alcohol, and especially 2-dimethylaminoethyl (meth)acrylate.
The invention also relates to polymers made with quaternized amino alkyl (meth)acrylates and use of said polymers in water treatment, sludge dewatering, papermaking process, agriculture, cosmetic and detergency composition, textile process, oil and gas recovery process such as enhanced oil recovery, fracturing, mining operation such as tailings treatment.
