High molecular weight unsaturated polyether macromonomer, and preparation method and application thereof
The invention provides a high molecular weight unsaturated polyether macromonomer which is characterized in that the polyether macromonomer is at a liquid state at normal temperature, and the structural formula (I) thereof is expressed in the specification, wherein R<1> is same or different, and represents a hydrogen atom or alkyl with 1-20 carbon atoms; R<2> represents alkyl with 1-20 carbon atoms; R<3> represents alkyl or carbonyl with 1-10 carbon atoms; R<5> represents a hydrogen atom or alkyl with 1-20 carbon atoms; R<4>O is different, and represents oxyalkenyl with 2-18 carbon atoms; n represents the average addition mole number of the oxyalkenyl, and 5<=n<=300; and X, Y and Z are same or different, and represent -N, -O or H. By optimally designing the molecular structure, the high molecular weight unsaturated polyether macromonomer provided by the invention ensures the liquid state thereof at normal temperature while the molecular polymerization reaction activity is ensured. Besides, a preparation method of the high molecular weight unsaturated polyether macromonomer provided by the invention is simple, and the conditions are easy to control; and the product does not need slicing post-treatment, the production cost is low, and the economic benefits are increased.
