    摘要： The present invention is related to high Impact strength thermoplastic compositions comprising: a) from 10 to 90% by weight of a rubber-modified monovinylidene aromatic (co)polymer; b) from 10 to 90% by weight of a polyphenylene ether; wherein: said rubber-modified monovinylidene aromatic (co)polymer a) comprising: I) a matrix comprising monovinylidene aromatic polymer, and II) from 5 to 25% by weight of rubber in the form of discrete rubber particles dispersed within the matrix, wherein the rubber particles comprise a blend of at least two polybutadienes as well as graft- and block copolymers of polybutadiene and monovinylidene aromatic polymer segments, said rubber particles exhibit: —an average particle size by volume (D50) comprised between 0.8 and 5.5 μm, measured by laser light scattering; said blend of at least two polybutadienes comprises: —at least 50% by weight of one or more polybutadiene(s) with a cis-1,4 structure content of at least 80% by weight and —at most 50% by weight of one or more polybutadiene(s) with a trans-1-4 structure content of at least 25% by weight and a 1,2-vinyl content of at least 5% by weight; said blend being characterized by a dynamic solution viscosity, comprised between 50 and 160 mPa·s, as determined by Brookfield viscometer according to ISO 2555 at a concentration of 5.43% by weight in toluene; and said polyphenylene ether b) has a repeating structural formula (I) wherein R1 and R2 are independently selected from the group consisting of a hydrogen atom, a halogen atom, C1-4 alkyl radicals, C1-4 alkoxy radicals, C6-10 aromatic radicals which are unsubstituted or substituted by a C1-4 alkyl radical, halohydrocarbon radicals having at least two carbon atoms between the halogen atom and the phenyl nucleus, hydrocarbonoxy radicals and halohydrocarbonoxy radicals having at least two carbon atoms between the halogen and the phenyl nucleus, and wherein n is an integer of at least 50. The invention further is related to a method for the preparation of the high Impact strength thermoplastic compositions.

    摘要： Provided is a resin composition having an excellent balance of high impact resistance and fluidity, and excellent ductile fracture properties. The resin composition contains: a polyphenylene ether resin (a); and a hydrogenated block copolymer (b) including a hydrogenated block copolymer component (b-1) that includes two polymer blocks A of mainly a vinyl aromatic compound and two polymer blocks B of mainly a conjugated diene compound, and a hydrogenated block copolymer component (b-2) that includes two polymer blocks A of mainly a vinyl aromatic compound and one polymer block B of mainly a conjugated diene compound, with a mass ratio of the hydrogenated block copolymer component (b-1) relative to the hydrogenated block copolymer component (b-2) (hydrogenated block copolymer component (b-1)/hydrogenated block copolymer component (b-2)) of 5/95 to 95/5. Polypropylene content in the resin composition is less than 5 mass % when all resin components are taken to be 100 mass %, in total.
