Summary:A process for preparing a structure rein­forced latex particle whose film has improved tensile and elongation properties prepared by an emulsion polymerization comprising a three-stage monomer feed addition. The second monomer feed is an amount from 5 to 30 parts per hundred parts monomer in said latex particle and is a polymer of which would have a Tg greater than either the first or third monomer feed. The subject structure reinforced latex particle pro­vides a film having improved tensile properties without a corresponding reduction in elongation. A pressure sensitive adhesive formulated with the structure rein­forced latex particle is also provided.
