Summary: | An aqueous emulsion is claimed, which crosslinks by a Michael addition reaction, yielding a crosslinked silicon modified organic composition upon removal of water. The aqueous emulsion comprises the product formed by mixing a polymer containing at least two Michael acceptor groups per polymer molecule, water, a surfactant and an effective amount of a crosslinker containing sufficient reactive hydrogen atoms of a Michael donor per crosslinker molecule or a precursor thereto. To obtain a crosslinked silicon modified organic composition upon the removal of water, the polymer or the crosslinker must contain at least one silicon atom. Our invention also includes a method for making these emulsions. |
