Abstract
(EN)
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.
(FR)
Ils sont représentés par la formule générale (I), dans laquelle ou bien PA = séquence polymère vinylaromatique ou méthacrylique; PB = séquence polymère acrylique; et PC, éventuellement présent, séquence polymère méthacrylique; ou bien PA et PC = séquence polymère issue d'un même monomère acrylique; et PB = séquence polymère méthacrylique; PD = séquence polymère vinylaromatique ou méthacrylique, et simultanément PE = séquence polymère acrylique; ou bien PD = séquence polymère acrylique, et simultanément PE = séquence polymère méthacrylique; n = nombre de branches de (PA-PB-PC), compris entre 2 et 20 inclus, et m = nombre de branches de (PD-PE), compris entre 0 et 18 inclus, avec n+m « 20, chaque branche (PA-PB-PC) et (PD-PE) pouvant ne comporter qu'une seule séquence polymère, les deux séquences étant alors différentes; et N = nodule réticulé d'au moins un monomère de réticulation multifonctionnel présentant au moins 2 doubles liaisons polymérisables par molécule. Application: selon le cas élastomères thermoplastiques, polymères thermoplastiques rigides choc, ou polymères renforcateurs choc.
