P the invention relates to compositions containing hydrogenated copolymers and of thermoplastic resins for engineering. / p & & p & in a composition containing a block copolymer, partially hydrogenated, a polycarbonate and at least one thermoplastic resin for engineering different, at least two of the polymers form between them of the networks intermixed continuous at least partial. / p & & p & the thermoplastic resins for mechanical construction engineering (for example) are a group of polymers having a set of properties, including the mechanical strength, the rigidity, the impact strength and the dimensional stability over a long period, which make them useful as construction materials. The thermoplastic resins for mechanical structures are especially advantageous to replace the metals because of the reduction in weight which can often be obtained, such as, for example, in applications in the automotive field. / p
