    Synthesis Of Hybrid Latex Polymer/Silica Through Emulsion Copolymerization With High Solids Content To Decorative Coating Production. The Development Of Organic/Inorganic Hybrid Latex By Incorporation Of Inorganic Particles Into Polymeric Matrix Via Emulsion Polymerization Has Received A Large Attention In Recent Years Due To The Benefits It Brings To The Final Product, Such As More Abrasion Resistance, Lack Of Emulsifier, And Deeper Perception Of Cleanliness By The Final User When Applied In Decorative Coatings. Hence, The Aim Of This Project Was To Develop A Strategic Synthesis Of Organic/Inorganic Hybrid Latex With High Solids Content As Well As Susceptible To Escalation Through Styrene Emulsion Polymerization With N-Butyl Acrylate (Abu) With The Presence Of Colloidal Silica Nanoparticles (Levasil" Cc 401) To Produce Decorative Coatings. It Was Applied Not Only Different Quantities Of Functional Monomer But Also Different Proportions Of Silica/Initiator, Silica/Monomers, As Well As Dosage Strategy Of Initi
