Abstract:
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.
