"The process to form partu00ecculas resin interpolu00ecmero, partu00ecculas resin article interpolu00ecmero, extruded, injection molded article after article, conformist,The structure in multiple layers, the composition of polu00ecmero, and process for producing articles with improved ESCR properties.Resin particles of interpolu00edmero composed of 20% to 60% by weight polyolefin not reticulate, e.g. polyethylene, polypropylene.And 40% to 80% by weight based on the weight of the particles of a vinyl aromatic monomer, e.g., styrene,That is polymerized in a process in suspension or form a inter penetrating network of polyolefin with vinyl aromatic monomer polymerized particles and having a gel content of from 0 to 1.5% by weight, based on the weight of the particles for improved processability in end use applications and improved ESCR properties.The resin particles of interpolu00edmero has a amolecimetno Vicat temperature of about 90 198 C to about 115 198 C, and an index of fusion of 0.2 to 3.0 g / 10 minutes (condition).The particles can be mixed with a blowing agent to form extruded foam articles, such as foam panel, and can be used in the processes of extrusion, injection molding,Roto molding, and thermo forming to form a layer, for example, sheet, film,And as a layer of union structures in multiple layers to connect adjacent layers consisting of incompatible polymers, that is,Polystyrene and polyethylene for improved rigidity in structures of multiple layers.
