Zusammenfassung:	PCT No. PCT/FR94/01360 Sec. 371 Date Jun. 12, 1995 Sec. 102(e) Date Jun. 12, 1995 PCT Filed Nov. 22, 1994 PCT Pub. No. WO95/15348 PCT Pub. Date Jun. 8, 1995The invention relates to polymer compositions of high impact strength, comprising a vinylaromatic polymer and a rubber, and to a process for their manufacture. These compositions are obtained by virtue of the use of two polybutadienes whose viscosities, measured at 25 DEG C. at a concentration of 5% in styrene, are, respectively, between 120 and 350 centipoises in the case of one and between 30 and 90 centipoises in the case of the other.
