Abstract
Block polymer compositions comprise: (a) a linear copolymer constituted by four alternating blocks, represented by formula (I) or (II> B1-T-A1-B2-A2 (I> or B1-A1-B2-T-A2 (II> wherein: B1 and B2 are polydienic preferably polybutadienic blocks A1 and A2 are polyvinylaromatic, preferably polystyrenic blocks T is a portion of random copolymer formed by dienic and vinylaromatic monomer units (b) a linear copolymer consitituted by two blocks, represented by formulae (III) or (IV> B3-T-A3 (III> or B3-A3 wherein: B3 is a polydienic block A3 is a polyvinylaromatic block and T has the above meaning. The polymeric composition, which can be blended with polystyrene, can be obtained both by blending the individual components, and by means of novel and original synthesis processes which make it possible both (A) and (B) components to be obtained simultaneously. The compositions have good impact strength, transparence and processability.
