Abstract
Abstract Highly thermal stable cross‐linking acrylate polymer latex of a long carbon chain monomer, that is, stearyl acrylate (SA) or octadecyl acrylate, has been successfully prepared by using sodium lauryl sulfate (SLS) emulsifier through emulsion polymerization. In this polymer chain reaction, methyl methacrylate (MMA) and ethyl acrylate (EA) are the monomers, while stearyl acrylate (SA) behaves as a functional monomer and potassium per‐sulfate (KPS) facilitates as the initiator. For this, different concentrations of functional monomer (SME1, SME2, SME3, SME4, and SME5) were used, and among the various concentrations, sample SME1 showed the highest thermal stability with 0.5% SA, 3.1% emulsifier, and 1.5% initiator concentration, respectively. The structure of monomers and synthesized products were optimized through Gaussian‐09 software. Additionally, the samples were characterized through FTIR, TGA, DSC, DLS, and NMR spectroscopy techniques for analyzing functionalization, thermal stability, molecular structure, particle size, and thermal transition. Finally, it has been observed that the synthesized acrylate polymer latex showed better binding capacity with concrete and significantly improved thermal behavior.
