摘要：
Homo- or copolymers A composed ofA.sub.1) 40-100% by weight of monomers of the general formula I ##STR1## A.sub.2) 0-60% by weight of monomers of the general formula II ##STR2## and A.sub.3) 0-10% by weight of further monomers capable of free radical polymerization,the percentages by weight of the monomers A.sub.1) to A.sub.3) summing to 100% andR.sup.1 and R.sup.4 being identical or different radicals and each being hydrogen or C.sub.1 -C.sub.4 -alkyl,R.sup.2, R.sup.3, R.sup.5, R.sup.6 being identical or different radicals and each being hydrogen or C.sub.1 -C.sub.4 -alkyl,with the proviso that at least two radicals from the group consisting of R.sup.1, R.sup.2 and R.sup.3 and from the group consisting of R.sup.4, R.sup.5 and R.sup.6 are hydrogen, andR.sup.7 is alkyl, cycloalkyl, aryl or aralkyl,are used as branching agents for amino-containing thermoplastic polymers.
