Abstract:
(DE) Verwendung von Homo- oder Copolymeren A, aufgebaut aus A1) 40-100 Gew.-% Monomeren der allgemeinen Formel (I); A2) 0-60 Gew.-% Monomeren der allgemeinen Formel (II); und A3) 0-10 Gew.-% weiteren radikalisch polymerisierbaren Monomeren, wobei die Gewichtsprozente der Monomeren A1) bis A3) 100 % ergeben und die Substituenten folgende Bedeutung haben: R1, R4 gleiche oder verschiedene Reste Wasserstoff oder C1 bis C4 Alkyl; R2, R3, R5, R6 gleiche oder verschiedene Reste Wasserstoff oder C1- bis C4-Alkyl; mit der Maßgabe, daß mindestens zwei Reste aus der Gruppe R1, R2, R3 und der Gruppe R4, R5, R6 Wasserstoff sind; R7 ein Alkyl-, Cycloalkyl-, Aryl- oder Aralkylrest bedeutet als Verzweiger für Aminogruppen enthaltende thermoplastische Polymere.
(EN) The invention concerns the use of homo- or copolymers A as branching agents for thermoplastic polymers containing amino groups. The homo- or copolymers A are composed of: A1) between 40 and 100 wt.% monomers of general formula (I); A2) between 0 and 60 wt.% of monomers of general formula (II); and A3) between 0 and 10 wt.% of further radically polymerizable monomers, the weight percentages of monomers A1) to A3) totalling 100 % and the substituents having the following meanings: R1, R4, which may be identical or different, designate the rests hydrogen or C1-C4 alkyl; R2, R3, R5, R6, which may be identical or different, designate the rests hydrogen or C1-C4 alkyl, provided that at least two rests from the group R1, R2, R3 and the group R4, R5, R6 are hydrogen; and R7 designates an alkyl, cycloalkyl, aryl or aralkyl rest.
(FR) L'invention concerne l'utilisation, comme agents de ramification pour des polymères thermoplastiques contenant des groupes amino, d'homo- ou de copolymères A comprenant: A1) entre 40 et 100 % en poids de monomères de la formule générale (I); A2) entre 0 et 60 % en poids de monomères de la formule générale (II); et A3) entre 0 et 10 % en poids d'autres monomères polymérisables par voie radicalaire, les pourcentages en poids des monomères A1) à A3) formant 100 % et les substituants ayant la notation suivante: R1, R4 désignent des restes hydrogène identiques ou différents ou alkyle C1 à C4, R2, R3, R5, R6 désignent des restes hydrogène identiques ou différents ou alkyle C1-C4, sous réserve qu'au moins deux restes du groupe R1, R2, R3 et du groupe R4, R5, R6 désignent hydrogène; R7 désigne un reste alkyle, cycloalkyle, aryle ou aralkyle.
