A resinous composition with resistance to environmental conditions, with heat resistance improved.

摘要

A resinous composition with resistance to environmental conditions, with heat resistance improved.Compositions are described comprising: (I) a rubber modified thermoplastic resin comprising a discontinuous elastomeric phase dispersed in a rigid elastomeric phase, and at least a part of rigid elastomeric phase is grafted in an elastomeric phase.And while the elastomeric phase comprises a polymer with structural units derived from at least one monomer (meth) acrylate alkyl (C ~ 1 ~ C ~ 12 ~); (II) a second polymer consisting mainly of structural units derived from at least one of the acrylate monomer (meta) Lquila (C ~ 1 ~ C ~ 12 ~)And optionally (III) a third polymer comprising structural units derived from at least one of alquenila aromatic monomer and at least one nitrile monomer with unsaturation monoetilu00eanica prepared in one step of polymerization separately and added in the composition. In Oct. Ras forms of implementation, the present invention includes articles made from these compositions.
