    摘要: Copolymers of ethylene have from 1 to 30 mol % of alkyl(meth)acrylates and, if desired, other comonomers, and have a residual comonomer content of less than 0.5% by weight in the copolymer. A process for preparing copolymers of this type in a combination of stirred autoclave and tubular reactor is described, as is the use of the copolymers for preparing polyamide molding compositions.
