Abstract
A method for the in-situ preparation of an ionic comonomer from its chemical precursors, prepared in a solution of styrene monomer is disclosed. In one embodiment, the ionic comonomer is zirconium methacrylate, Zr(MA)4 or zirconyl methacrylate, ZrO(MA)2, or a combination thereof, and zirconium carbonate hydroxide oxide, ZrCO3(OH)2.ZrO2, and methacrylic acid, CH2═C(CH3)—COOH, are used as precursors used for its in-situ preparation.
Claims21
A method for the in-situ preparation of an ionic comonomer in styrene monomer comprising:
- contacting chemical precursors of an ionic comonomer in a reaction vessel containing styrene monomer;
- and
- producing a first product comprising the ionic comonomer in solution with the styrene monomer.
A method for the in-situ preparation of an ionic comonomer in styrene monomer comprising:
- contacting zirconium carbonate hydroxide oxide, ZrCO3(OH)2.ZrO2, and methacrylic acid, CH2═C(CH3)—COOH, in a molar ratio of zirconium to methacrylic acid from 1:1 to 1:10, in a reaction vessel containing styrene monomer;
- and
- producing a first product comprising either zirconium methacrylate, Zr(MA)4, or zirconyl methacrylate, ZrO(MA)2, or a combination thereof, in solution with the styrene monomer.
