Latices were synthesized using butyl acrylate(BA), ethyl acrylate(EA), ethyl methacrylate(EMA), methyl methacrylate(MMA) and styrene(St) separately. And blends of these latices were prepared and then films were made. The effects of the selection of monomer, ratio of copolymer and ratio of blending on the damping properties of the materials were studied. The results indicate that the blends of multi gradient T g polymer have a good damping property. Furthermore, PMMA is better than P(St BA) as a hard ...
