Graft- and core-shell-copolymers with an improved phase bond between the graft base and the grafted polymer phase are disclosed. as well as the peroxide group-containing copolymers upon which they are based and a process for producing said polymers. The graft- and core-shell copolymers are made from a peroxide group-containing polymer phase which contains an olefinically bi-unsaturated peroxide compound having the formula H2C = CH-O-CO-R1-CO-O-O-CO-R1-CO-O-CH = CH2 in which R1 stands for a chemical bond, for a linear or branched alkyl chain with 1 to 10 C atoms, for a cycloalkyl group with 3 to 10 C atoms or for an aromatic compound with 6 to 14 C atoms.
Divulgation concernant des copolymères de type greffe et noyau-coquille, avec une liaison phasique améliorée entre la base de greffe et la phase de polymère greffé, ainsi que les copolymères de base renfermant le groupe peroxyde et un procédé pour l'obtention desdits polymères. Les copolymères de type greffe et noyau-coquille sont obtenus à partir d'une phase polymérique renfermant le groupe peroxyde, laquelle contient un composé peroxydique bi-insaturé oléfinique de formule H2C = CH-O-CO-R1-CO-O-O-CO-R1-CO-O-CH = CH2, où R1 représente une liaison chimique, un alkyle linéaire ou ramifié de 1 à 10 atomes de C, un groupe cycloalkyle de 3 à 10 atomes de C, ou un composé aromatique de 6 à 14 atomes de C.
