1. , based on the transparent composition of high-impact vinyl aromatic copolymers, comprise:

  • A () 90-99wt% comprises the high-impact vinyl aromatic copolymers of hard substrate, the vi-ny l aromatic monomers that this hard substrate is combined by 50-70wt% at least one, (methyl) acrylic acid ester that the olefinically unsaturated nitriles that 20-40wt% combines and 0-20wt% at least one combine is formed, the matrix of this matrix 1-25wt% elasticity phase that has been wherein dispersed relative to the gross weight of described high-impact vinyl aromatic copolymers, it is described that to be dispersed in elasticity in the polymeric matrix of component (a) by butadiene content be that the styrene-butadiene random of 40-55wt% or segmented copolymer are formed,B lubricating oil that () 1-10wt% is made up of the polyester of hexanodioic acid and alkyl diol, wherein this alkyl has 2-6 carbon atom, and this lubricating oil has the viscosity of 2-20Pasec at 25 DEG C.
