A variety of reactive ethylenically unsaturated compounds such as acrylate derivatives can be used including, but not limited to, (meth) acrylic acid, (meth) acryloyl chloride, (meth) acrylic anhydride, and 2-isocyanatoethyl (meth) acrylate.
The monomer is prepared by reacting the mono- or di-functional alkylene oxide (co) polymer with (meth) acrylic anhydride.
