Abstract
Promoters for a crosslinking reaction involved in the curing of a system comprising crosslinkable polymers are bound to polymeric microparticles having a diameter of about 0.01 to 6 microns prepared by polymerizing a mixture of ethylenically unsaturated monomers. The microparticles carrying the crosslinking reaction promoter may be incorporated to coating compositions, printing inks, sealants, adhesives and other polymeric products in place of conventional crosslinking reaction promoters.
