    摘要： A process for the preparation of copolymers of ethylene and dicarboxylic acid in the presence of a free-radical inhibitor. The process comprises of warming a mixture of ethylene and C.sub.3 -C.sub.6 -alkenecarboxylic acid to a temperature of from 60.degree. to 100.degree. C. before addition of the free-radical inhibitor. The maximum polymerization temperature to recover said copolymers of ethylene is in the range of from 100.degree. to 260.degree. C.; and wherein said copolymer comprises from 94 to 99.5 mol % of ethylene and from 0.5 to 6.0 mol % of C.sub.3 -C.sub.6 -alkenecarboxylic acid.

    摘要： Copolymers of ethylene with .alpha.,.beta.-unsaturated carboxylic acids are prepared at from 50.degree. to 250.degree. C. and from 500 to 5000 bar in a stirred autoclave having a length/diameter ratio greater than 5:1 by a process in which the monomer mixtures are fed into the autoclave in at least two part-streams, the first part-stream being passed into the autoclave at the beginning of the autoclave pipe and the second part-stream being introduced at a position which is a distance away from the beginning which corresponds to 25-50% of the total length and the amount of the .alpha.,.beta.-unsaturated carboxylic acids in the first part-stream is from 20 to 90% less than the average amount in the further part-streams and a peroxide polymerization initiator having a lower decomposition temperature, or a mixture of peroxide polymerization initiators having a lower average decomposition temperature, than that of the initiators in the further part-streams is passed in with the first part-stream.

    摘要： Carboxyl-containing copolymers of ethylene are prepared by polymer-analogous pyrolytic ester cleavage of copolymers consisting ofa) from 60 to 99.9 mol% of ethylene,b) from 0.1 to 40 mol% of C.sub.4 -C.sub.8 -tert-alkyl esters of copolymerizable C.sub.3 -C.sub.12 -carboxylic acids andc) from 0 to 20 mol% of further copolymerizable monomers by a method in which pyrolytic ester cleavage is carried out at from 150.degree. to 250.degree. C. in the presence of organic sulfonic acids, in the absence of a solvent and in the virtual absence of free radical initiators.
