摘要： The present invention relates to a panel made of plaster, in particular of the type comprising a plaster core arranged between two sheets of paper or non-woven material, in which said core includes at least one polymer selected from: polyvinyl butyral (PVB); copolymers of vinyl acetate and an olefin, said copolymers having a glass transition temperature which ranges from -10 to +25 °C; terpolymers of vinyl acetate, an olefin and a vinyl ester monomer; terpolymers of vinyl acetate, a vinyl ester monomer and a (meth)acrylate monomer; and copolymers of vinyl acetate and an acrylic monomer. The subject matter of the invention also includes a method for production of said panel, the use of said polymer to improve the acoustic performance of said panel and the above-mentioned composition made of plaster.
