Abstract

The copolymers described are represented by general formula (I), in which either PA = a vinylaromatic or methacrylic polymer sequence; PB = an acrylic polymer sequence; and PC, possibly present, a methacrylic polymer sequence; or PA and PC = a polymer sequence stemming from the same acrylic monomer; and PB = a methacrylic polymer sequence; PD = a vinylaromatic or methacrylic polymer sequence, and simultaneously PE = an acrylic polymer sequence; or PD = an acrylic polymer sequence, and simultaneously PE = a methacrylic polymer sequence; n = number of branches of (PA-PB-PC), between 2 and 20 inclusive and m = number of branches of (PD-PE) between 0 and 18 inclusive, with n+m </= 20, each branch (PA-PB-PC) and (PD-PE) comprising only one polymer sequence, the two sequences then being different; and N = cross-linked nodule of at least one multifunctional reticulation monomer presenting at least two double polymerisable bonds per molecule. Application: either thermoplastic elastomers, shock type rigid thermoplastic polymers or shock type reinforcement polymers.
