摘要:
Vinyl aromatic (co) polymer reinforced with a rubber selected from a linear diene rubber (i) with a solution viscosity lower than 70 cPs; a partially radial diene rubber (ii), with a solution viscosity lower than 70 cPs; a three-chain diene rubber (iii) with a solution viscosity lower than 70 cPs; a blend of linear diene rubbers (i) and radial diene rubbers (iv) in a maximum ratio between them (i)/(iv) of between 99.5/0.5 and 85/15.
