| Abstract: | Heat-sensitive microcapsules were prepared by emulsion polymerization with the leucocompound as a core material and methyl methacrylate and unsaturated hyperbranched poly(amide-ester) as wall-forming materials.The effects of the reaction parameters on the particle size and the encapsulation efficiency of the microcapsules were investigated.The FTIR analysis of microcapsules demonstrated that leucocompound was successfully encapsulated in the crosslinked PMMA matrix.The prepared microcapsules have good dispe... |
