In this work, we have successfully synthesized epoxidized poly(styrene-blockbutadiene-block-styrene) with the highest epoxidation degree (55 mol%) for the first time by using metachloroperbenzoic acid method. This highly epoxidized styrene-butadiene-styrene (eSBS) block copolymer exhibited good compatibility with the epoxy (diglycidylether of bisphenol-A)/ eSBS block copolymer-4,4 0-diamino diphenyl methane blend. Transmission electron microscope images showed that the eSBS block copolymer formed spherical nanostructure morphology within the blend due to reaction induced phase separation. The addition of eSBS block copolymer in the system significantly improved the wetting parameters such as hydrophilicity, surface free energy, work of adhesion, spreading coefficient and Girifalco-Good's interaction parameter values, which are discussed in detail. The as-prepared selfassembled nanostructured epoxy system will be useful in highly toughened coating applications such as aircraft, automobile, and flooring industries.

Poly acrylic siloxane coatings are generating a lot of interest due to their high durability and superior performance properties in different applications. The study presented here is on the synthesis and characterization of siloxane containing styrene-acrylic/acrylic latex systems through emulsion polymerization. The polymers have been characterized for their physical, chemical, thermal and surface properties using different characterizing techniques like FTIR, DSC, SEM, DLS and Contact angle measurements. The incorporation of siloxane in the polymers was found to improve properties such as hydrophobicity and film formation. The paints prepared using the hybrid polymers as binders exhibited superior performance properties like weather ability, Dirt pick up resistance and mechanical properties.
