This paper was aimed at preparing broad damping temperature rang, high tanS vibration damping materials. Homopolymer/copolymer blends, LIPN blends and designed Tg copolymer blends were studied separately. Dynamic Mechanical Analysis(DMA) was used to test the damping properties of materials.
Various poly(meth)acrylate (PMMA, PEMA, PnBMA, PMA, PEA, PDA) and PS homopolymer or copolymer latexes were prepared via normal emulsion polymerization. These latexes were blent according to the formula, then sa...
