Herein, a series of microcapsules containing hexadecane with PMMA and poly (MMA-co-BA) shell were synthesized by suspension polymerization. The effect of BA composition of shell on thermal properties of microcapsules was studies. Melting enthalpy and thermal properties were evaluated by DSC. Thermal cycling performance of the samples was evaluated by DSC and leakage of HD was observed in microcapsules containing high BA content. Thermal stability was measured by TGA analysis. Different degradation processes was observed for samples.
