    摘要: A process is described for copolymerizing ethylene with vinyl esters and, if desired, with further vinylic comonomers in a tube reactor at pressures of from 500 to 4000 bar and at not more than 220° C., which comprises initiating the free-radical polymerization at at least two locations of the tube reactor by adding a catalyst/initiator and adjusting the temperature profile within the reactor such that the temperature maxima downstream of the initiation locations are from 150 to 220° C. and differ by less than ±10° C. from one another.

    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.
