    摘要: The subject of this invention is acrylic polymer plastisol compositions, wherein the acrylic polymer component of the plastisol composition is a single-stage methyl methacrylate copolymer derived from methyl methacrylate and a comonomer component comprising isobutyl methacrylate and optionally other comonomer(s). The selection of isobutyl methacrylate as a comonomer with the methyl methacrylate results in good compatibility with a wide range of plasticizers and without undue softness in the resulting plastisol.
