A STRUCTURED REACTIVE LATEX.

摘要

A latex comprising a free radically polymerized product, said product comprising at least two ethylenically unsaturated monomers, at least one of said monomers having an isocyanate group which is sterically hindered or blocked and at least one other of said ethylenically unsaturated monomers being free of isocyanate functional groups, in an aqueous emulsion in the presence ofa free-radical polymerization catalyst, in a manner such that the sterically hindered or blocked isocyanate groups distribute in the outer layer of the latex particle and the method of making such.
