"Expansu00ecveis expanded polymeric compositions, articles,Processes for the preparation of compositions expansu00ecveis based on aromatic polu00ecmeros and preparation in mass contu00ecnua of polu00ecmeros vinyl aromatic expansu00ecveis,The use of polu00ecmeros vinyl aromatic vinyl aromatic expansu00ecveis, polu00ecmeros and expansibility improved, and expansu00ecveis accounts of polu00ecmeros vinyl aromatic.Expandable vinyl aromatic polymer compositions which contain a polymer with at least one vinyl aromatic monomer having an average molecular weight Mw in the range from 50000 to 170.000,It comprises: (a) 0 to 50% by weight of a copolymer obtained by polymerization of one or more vinyl aromatic monomers and 0 1 to 15% by weight of a 244 alquilestireno; (b) 0 to 10% by weight of a polymer.Compatible having a crystallinity of less than 10% and a glass transition temperature (TG) of more than 100 198 C,The remaining percentage consisting of vinyl aromatic polymer; and (c) 2 to 10% by weight, calculated with respect to the total, a blowing agent,Since at least one between (a) and (b) is present in the polymer blends.
