Heat/light stable interpenetrating polymer network latexes.

摘要

An interpenetrating polymer network latex exhibiting heat and light stability and good mechanical properties comprising, a cross-linked hydrophilic polymer newtork having at least one monovinyl monomer and at least one polyvinyl cross-linking monomer, and a hydrophobic polymer domain having at least one open chain conjugated diene monomer and/or at least one other hydrophobic monovinyl monomer, wherein the hydrophobic polymer domain is emulsion polymerized in the cross-linked hydrophilic polymer network such that the hydrophilic polymer network forms a continuous phase; and the hydrophobic polymer domain forms a discontinuous but mutually exclusive microdomain with each latex particle.
